Are the­re any merits con­nec­ted with using SaaS based solu­ti­ons? If you are plan­ning to use soft­ware deve­lo­p­ment ser­vice in your busi­ness, this review will offer five rea­sons why you should go for SaaS solu­ti­ons. The SaaS app­li­ca­ti­ons run on ser­vers of dif­fe­rent SaaS users and pro­vi­ders and are acces­si­ble through brow­sers. Rather than purcha­sing an app­li­ca­ti­on, as a user you pay a rent’, which allows you to uti­li­ze SaaS for a cer­tain peri­od of time. This means you will be able to redu­ce the use cost overtime. 

What are SaaS Based Solutions?

SaaS i.e. soft­ware as a ser­vice refers to a mode of soft­ware dis­tri­bu­ti­on wher­eby a third-par­ty pro­vi­der often hosts apps and makes them rea­di­ly avail­ab­le to dif­fe­rent cli­ents online. Soft­ware as a ser­vice is among the three prime clas­ses of cloud com­pu­ting, apace with PaaS (plat­form as a ser­vice) and IaaS (infra­st­ruc­tu­re as a ser­vice). Some of the examp­les of SaaS inclu­de GoTo­Mee­ting, Com­mon SaaS Use-Case and Goog­le Apps among others. Here are rea­sons showing why you should go for SaaS based solu­ti­ons when the need arises:

5 Rea­sons Why You Should Go for SaaS Based Solutions 

Lower Up-front Cost

SaaS gene­ral­ly is sub­scrip­ti­on-based not to men­ti­on it does not car­ry any up-front licen­se char­ges, which makes it pos­sess a lower initi­al cost. The manage­ment of the IT infra­st­ruc­tu­re which runs the soft­ware is per­for­med by the SaaS pro­vi­der and the­re­fo­re the char­ges for soft­ware and hard­ware main­ten­an­ce are very low.

Easy Upgrades

Easy upgrades solu­ti­on is ano­t­her merit that makes SaaS a sui­ta­ble alter­na­ti­ve over the con­ven­tio­nal models of soft­ware instal­la­ti­on. With this app­li­ca­ti­on, the SaaS pro­vi­der will help in tack­ling the soft­ware and hard­ware updates for you. The pro­vi­der deploys upgrades to the hos­ted apps and hence remo­ves this respon­si­bi­li­ty and workload from you.

Acces­si­bi­li­ty and Scalability

In order to obtain a SaaS app­li­ca­ti­on, an inter­net con­nec­tion and a brow­ser is all you requi­re to have. The­se things are gene­ral­ly pre­sent on a wide array of gad­gets and from any place glo­bal­ly, which makes SaaS to be easi­ly acces­si­ble when com­pa­red to the con­ven­tio­nal busi­ness software.

SaaS pro­vi­ders pro­vi­de a ran­ge of sub­scrip­ti­on alter­na­ti­ves and fle­xi­bi­li­ty to adjust sub­scrip­ti­ons when and as nee­ded. The­re­fo­re, with SaaS based solu­ti­ons, as your tra­de grows or when num­ber of users that requi­re acqui­ring the ser­vices incre­a­se, you can chan­ge sub­scrip­ti­ons easily.

Set­ting up and Deploy­ing SaaS is Quick

SaaS as an app­li­ca­ti­on is not only alrea­dy instal­led in the cloud, but con­fi­gu­red also. By SaaS being quick and easy to set up and deploy, this hel­ps mini­mi­ze typi­cal delays which often result from leng­thy con­ven­tio­nal soft­ware deve­lo­p­ment applications. 

It is Cost-Effec­ti­ve Alter­na­ti­ve Generally

SaaS can offer nota­ble savings due to several fac­tors. For instance, it can help you eli­mi­na­te the upfront pri­ce of installation/purchase, and on-going cos­ts such as upgrades and main­ten­an­ce. Rather than spen­ding huge amounts of cash on hard­ware instal­la­ti­on, SaaS based solu­ti­ons can be down­loa­ded as well as main­tai­ned easily.

Bot­tom Line 

Uti­li­zing SaaS based solu­ti­ons in your busi­ness can help you save both time and money. Using SaaS is the­re­fo­re worthy sin­ce you will be expo­sed to a ran­ge of merits. Fur­ther­mo­re, unli­ke the con­ven­tio­nal soft­ware deve­lo­p­ment app­li­ca­ti­ons, the main­ten­an­ce respon­si­bi­li­ties of SaaS solu­ti­ons will not be hand­led by your IT depart­ment, but by the ven­dor themselves. 

Every soft­ware deve­lo­p­ment com­pa­ny out the­re knows, that no mat­ter how polis­hed your inter­nal pro­ces­ses are, things never go as expec­ted. Soft­ware deve­lo­p­ment is one of the most chal­len­ging and at the same time com­pe­ti­ti­ve indus­tries today.

So natu­ral­ly, every major busi­ness in this field stri­ves to impro­ve its pro­duc­ti­vi­ty and opti­mi­ze work­flows to over­co­me most com­mon challenges.

But what exact­ly are tho­se challenges?

  1. Assemb­ling requirements

Poor­ly defi­ned requi­re­ments come down to simp­le “Gar­ba­ge in. Gar­ba­ge out”. The dif­fi­cul­ty in requi­re­ments gathe­ring almost always asso­cia­ted with mis­com­mu­ni­ca­ti­on bet­ween cli­ent and soft­ware deve­lo­p­ment vendor.

Some­ti­mes the cli­ent lacks cer­tain tech­ni­cal exper­ti­se and the­re­fo­re puts in front over­ly-opti­mistic expec­ta­ti­ons. Some­ti­mes soft­ware deve­lo­pers can­not trans­la­te tech­no­lo­gi­cal limi­ta­ti­ons into busi­ness per­spec­ti­ve. Regard­less of why it hap­pens, made-pro­ject chan­ges in requi­re­ments always cau­se delays, revi­si­ons and addi­tio­nal expenses.

  1. Esti­ma­ti­on & road­map planning

Esti­ma­ti­on of cost and clear plan­ning hap­pens at the very ear­ly sta­ges of pro­duct lifecy­cle. And we all know that it is impos­si­ble to account for ever­ything. It’s always a dif­fi­cult task when you have to exp­lain to the cli­ent that some dead­line needs to be exten­ded. So it’s very important to estab­lish maxi­mum trans­pa­ren­cy bet­ween two par­ties and keep com­mu­ni­ca­ti­on lines on at all times.

  1. Stay­ing on top of the technology

This one is a clear respon­si­bi­li­ty of soft­ware deve­lo­p­ment com­pa­ny. Stay­ing on top of tech trends and be able to accom­mo­da­te most inno­va­ti­ve busi­ness requests is very important becau­se the tech­no­lo­gy chan­ges at a rapid pace. That is why it falls down on com­pa­nies to con­ti­nuous­ly edu­ca­te their employees and make sure that they as a busi­ness stay competitive.

  1. Mul­ti­ple tes­ting & QA iterations

The best com­pa­nies in soft­ware deve­lo­p­ment sec­tor have rea­li­zed long ago that Tes­ting and QA should never come as an afterthought or post-pro­duc­tion pro­cess. Various ite­ra­ti­ons of tes­ting need to occur throughout the pro­ject cycle. 

And when you inves­ti­ga­te the ent­i­re sys­tem, the­re will be bugs found. Many times the pro­blem needs to be iso­la­ted to let the rest of the pro­ject move on. But in some cases, it is sim­ply impos­si­ble and you reach a com­ple­te road­block that slows down the deve­lo­p­ment time.

Intech­Core Soft­ware Deve­lo­p­ment Services

Only by employ­ing inno­va­ti­ve metho­do­lo­gy in mana­ging remo­te teams and stay­ing on top of trends can soft­ware deve­lo­p­ment com­pa­ny sur­vi­ve in the com­pe­ti­ti­ve mar­ket. Here at Intech­Core, we struc­tu­re our inter­nal work­flows deli­ver excep­tio­nal results, infor­ma­ti­on secu­ri­ty and incre­a­sed productivity.

Every day we work towards over­co­m­ing industry’s big­gest chal­len­ges and deli­vering our cus­to­mers the excep­tio­nal-qua­li­ty soft­ware. We pri­de our­sel­ves on suc­cee­ding in most deman­ding pro­jects through con­ti­nuous moni­to­ring of pro­gress, cost, and delivery.


Nowa­days, the pro­of of con­cept (POC) has beco­me more or less a stan­dard pro­ce­du­re in most soft­ware deve­lo­p­ment com­pa­nies. POC is used to assess the via­bi­li­ty of a pro­duct in a real mar­ket envi­ron­ment, whe­re true busi­ness needs exist. In one of our pre­vious arti­cles, we’ve alrea­dy cove­r­ed how to struc­tu­re POC and what goes into it exactly.

Today we’ll go bey­ond simp­le requi­re­ments and pro­ces­ses and talk about set­ting your busi­ness goals strai­ght in order to deli­ver the POC, your cus­to­mers will appreciate.

One con­ver­sa­ti­on that is often mis­sed, when tal­king about POC, is how is it actual­ly bene­fit the cli­ent? So here at Intech­Core, we’ve com­pi­led a small check­list to help you stay on track and think cus­to­mer-first during the pro­of of concept.

Iden­ti­fy Decisi­on Makers

Note: decisi­on makerS.

Very often, most com­pa­nies only envi­si­on their cli­ent as a sin­gle per­son with whom they com­mu­ni­ca­te. But most busi­nes­ses don’t func­tion in such tota­li­ta­ri­an regime. The­re are mul­ti­ple peop­le who run the com­pa­ny and influ­ence the final decision:

  • Busi­ness owner
  • CTO (chief tech­ni­cal officer)
  • Finan­cial manager
  • Mar­ke­ting lead
  • Etc.

In order for you to deli­ver and pre­sent tru­ly stel­lar POC, you need to think about how all the­se peop­le will see it. Becau­se if you pro­ve that the pro­duct in mind has an incredi­ble tech­ni­cal app­li­ca­ti­on but don’t pre­sent a clear mean of mar­ke­ting it, the who­le pro­ject might be in jeopardy.

Defi­ne Suc­cess & Align Expectation

Perhaps the most important aspect that is get­ting mis­sed all the time. You’ve hel­ped your cli­ent launch MVP (mini­mum via­ble pro­duct), and you gather some feed­back. What comes next? You haven’t actual­ly defi­ned any mea­sura­ble cri­te­ria of suc­cess. Here are a cou­p­le of ques­ti­ons you might want to ask yourself and cli­ent befo­re even starting:

  • Why are we doing this and what are we try­ing to achieve?
  • Which other pro­duct on the mar­ket are we com­pe­ting against?
  • With what other soft­ware can we com­pa­re the product?
  • Wha­t’s right or wrong with the way we launch MVP?
  • Wha­t’s the real value of the product?
  • Who will main­tain and upkeep the product?

By asking the­se ques­ti­on, both you and the cli­ent might unco­ver some pre­vious­ly obscu­red chal­len­ges or prospects.

Also, the­se ques­ti­ons will help you in aligning expec­ta­ti­ons with cus­to­mers and avoiding the situa­ti­on whe­re the cli­ent has unrea­listic forecast.

Know What to Do Next

After a suc­cess­ful com­ple­ti­on of POC, for a soft­ware deve­lo­p­ment com­pa­ny, the logi­cal next step is recei­ving a paycheck. But it doesn’t have to be this way. Having bet­ter cla­ri­ty on the next steps requi­red by each par­ty incre­a­ses the trust bet­ween com­pa­nies and streng­t­hens their partnership.

If you do a bit of extra work and stri­ve to go bey­ond simp­le MVP launch, then you might find yourself in a posi­ti­on, whe­re you have a loy­al cus­to­mer base who ent­rust you with their future pro­jects and will men­ti­on you as a trus­ted part­ner in the future.


Are you plan­ning to hire a cus­tom soft­ware app­li­ca­ti­on deve­lo­p­ment com­pa­ny soon and sear­ching for tricks which can help you secu­re a repu­ta­ble firm that will assu­re you with top-notch solu­ti­ons that suit your needs? If so, this review will aid you on how to avoid being foo­led by a cus­tom soft­ware deve­lo­p­ment com­pa­ny. Cus­tom soft­ware deve­lo­p­ment firm is a kind of com­pa­ny that spe­cia­li­zes in designing soft­ware app­li­ca­ti­ons often to a par­ti­cu­lar user or cate­go­ry of users wit­hin insti­tu­ti­ons. The soft­ware desi­gned is inten­ded to address the various needs of the users. 

Cur­r­ent­ly, the mar­ket niche for cus­tom soft­ware deve­lo­p­ment firms is occu­p­ied with both legit and expe­ri­en­ced com­pa­nies and the unre­li­able ones. The­re­fo­re, pri­or to ent­rus­ting any firm with your cus­tom soft­ware deve­lo­p­ment needs, it is ide­al you rese­arch care­ful­ly on the various com­pa­ny choices you find first. 

A good rese­arch will help dif­fe­ren­tia­te bet­ween the reli­able cus­tom deve­lo­p­ment firms from the fake ones. Cour­te­sy of rese­ar­ching, you will also get a repu­ta­ble cus­tom deve­lo­p­ment com­pa­ny which will pro­mi­se you with top-notch and afford­a­ble solu­ti­ons and extre­me­ly depen­da­ble terms of service.

How to Avoid Being Foo­led by a Cus­tom Soft­ware Deve­lo­p­ment Company

First, in your attempt to avoid being foo­led by a cus­tom soft­ware deve­lo­p­ment firm, it is vital you know what roles the­se kind of com­pa­nies per­form. A good com­pa­ny is one which will ensu­re you get solu­ti­ons which will lea­ve you with a uni­que and com­plex web­site or mobi­le apps which sup­ports your mar­ke­ting cam­pai­gns as well as other busi­ness objec­ti­ves. Here are some of the issu­es most peop­le expe­ri­ence once they out­sour­ce the ser­vices of a cus­tom soft­ware deve­lo­p­ment com­pa­ny, which will help you avoid being foo­led if you plan to hire one soon:

1. Cus­tom Might Sim­ply Indi­ca­te Slight­ly’ Modified 

Some firms clai­ming to be pro­vi­ding cus­tom soft­ware deve­lo­p­ment solu­ti­ons offer merely minor-to-major imple­men­ta­ti­ons and modi­fi­ca­ti­ons of stan­dard ser­vices. It is vital that the firm you choo­se is one pro­vi­ding tem­pla­tes that are well writ­ten, easi­ly cus­to­miz­ab­le and scala­b­le. This is important sin­ce it will help you later if you will con­si­der making a web overhaul. 

2. Any Deve­lo­per May Claim to Con­struct Cus­tom Software

Pro­vi­ded the deve­lo­per can make chan­ges to the source code of soft­ware, they will claim to be doing cus­tom soft­ware deve­lo­p­ment. This is not right. The­se are only but mere modi­fi­ca­ti­ons that can­not make soft­ware uni­que and very reli­able. It is recom­men­ded that the cus­tom soft­ware deve­lo­p­ment com­pa­ny you choo­se is one capa­ble of hand­ling all major modi­fi­ca­ti­ons that will make you attain uni­que as well as supe­ri­or qua­li­ty soft­ware solu­ti­ons.
The com­pa­ny you select must make the app­li­ca­ti­on from scratch and without uti­li­zing any rea­dy-made solutions. 

The Best Way to Secu­re a Repu­ta­ble Cus­tom Soft­ware App­li­ca­ti­on Deve­lo­p­ment Company

You must make sure that if the com­pa­ny you liai­se with will use rea­dy-made soft­ware, you know what the soft­ware is and the pur­po­ses it will ser­ve in your busi­ness. Make sure also you ask what impli­ca­ti­ons for future cus­to­miza­bi­li­ty and sca­la­bi­li­ty the soft­ware which will be made for you by the firm you opt to con­si­der will offer. 

A pro­gramming lan­guage refers to a set of inst­ruc­tions, com­man­ds as well as other syn­tax uti­li­zed to con­struct a soft­ware pro­gram. It is a set and voca­bu­la­ry of gram­ma­ti­cal rules which are inten­ded to inst­ruct a com­pu­ter to car­ry out some spe­ci­fic tasks. 

Based on fact-fin­dings, one of the most essen­ti­al skills to learn in our pre­sent-day world is to know how to wri­te appro­pria­te­ly a com­pu­ter pro­gram. Cur­r­ent­ly, com­pu­ters are being uti­li­zed in almost every com­pa­ny. This is becau­se they are excee­din­gly bene­fi­cial in mat­ters per­tai­ning assis­ting a firm to sca­le up accord­in­gly. This makes the need to learn pro­gramming lan­guages come handy. 

Howe­ver, the mar­ket niche for pro­gramming lan­guage is fil­led with a wide array of lan­guage opti­ons. The­re­fo­re, it is vital you do your home­work accord­in­gly so that you can know the kind of pro­gramming lan­guage that will be hel­pful with your needs befo­re you start lear­ning any. Here are some of the top-notch pro­gramming lan­guages to learn in 2019:

Which Pro­gramming Lan­guage to Learn in 2019

1: Java

Java is a pro­gramming lan­guage that is most­ly uti­li­zed in lar­ge insti­tu­ti­ons and its effec­ti­ve­ness has made it stand the tas­te of time. This kind of pro­gramming lan­guage is wide­ly uti­li­zed for con­struc­ting enter­pri­se-sca­le web­site app­li­ca­ti­ons. One of the inor­di­na­te fea­tures rela­ted to using Java is that it is excee­din­gly sta­ble; a fac­tor that has con­tri­bu­t­ed to majo­ri­ty of the lar­ge enter­pri­ses to adopt it.

If you are hun­ting for a deve­lo­p­ment based work at a lar­ge insti­tu­ti­on, it is recom­men­ded you con­si­der lear­ning Java. 

#2: Java­Script

Java­Script which is also cal­led the fron­ted pro­gramming lan­guage is com­mon­ly uti­li­zed for designing inter­ac­ti­ve front­end app­li­ca­ti­ons. A good examp­le of Java­Script lan­guage inclu­de, when a per­son clicks a but­ton on a com­pu­ter that opens up a pop-up. In case of this sce­n­a­rio, the logic is exe­cu­t­ed through JavaScript. 

3: Swift

Swift is a pro­gramming lan­guage which is main­ly used for deve­lo­ping iOS app­li­ca­ti­ons. It is a kind of pro­gramming lan­guage that is con­si­de­red an ide­al opti­on to learn sin­ce the popu­la­ri­ty of iOS based gad­gets is incre­a­sing each and every day. For instance, iPho­ne has mana­ged to occu­py a huge mar­ket share and thus giving Android a stiff com­pe­ti­ti­on. The­re­fo­re, if you desi­re to ser­ve this mar­ket niche, it is advi­s­able you con­si­der lear­ning Swift programming. 

4: PHP

PHP is amongst the most famous pro­gramming lan­guages that can­not be acces­sed direct­ly by a com­pu­ter user. Though most peop­le con­si­der it a nas­ty lan­guage, it is very easy to learn PHP. If you desi­re working at an old insti­tu­ti­on as a backend com­pu­ter deve­lo­per, it is vital you con­si­der lea­ning PHP programming.

5: R

R is a pro­gramming lan­guage com­mon­ly uti­li­zed for Machi­ne Lear­ning and Data Ana­ly­sis. It is a pro­gramming lan­guage that can pro­vi­de a gre­at frame­work as well as built-in libra­ries for deve­lo­ping strong Machi­ne Lear­ning algorithms. 

R can also be used for sta­tis­ti­cal com­pu­ting and is an appro­pria­te lan­guage for tho­se peop­le who want to work as ana­ly­tics in lar­ge institutions.

Bot­tom Line

Sin­ce not­hing comes easy, make sure you put a lot of effort by rese­ar­ching exten­si­ve­ly in your attempt to be more know­led­ge­ab­le and infor­med about the afo­re­men­tio­ned pro­gramming lan­guages. This will help you beco­me a pro at using them and thus bene­fit from what they offer in the job market.

What sta­ges of soft­ware deve­lo­p­ment should you accom­plish when taking a care­er in this line of pro­fes­si­on? A soft­ware deve­lo­per is an expert con­cer­ned with aspects of soft­ware deve­lo­p­ment pro­ce­du­re, which inclu­des rese­ar­ching, designing, pro­gramming as well as tes­ting of the com­pu­ter soft­ware. Though most soft­ware deve­lo­pers deve­lop the app­li­ca­ti­ons which enab­le peop­le to accom­plish pro­jects on a com­pu­ter or other devices, the­re are others who are respon­si­ble for deve­lo­ping the under­ly­ing struc­tures which con­trol net­works or run the devices.

Once you suc­cess­ful­ly com­ple­te a soft­ware deve­lo­p­ment care­er, as a com­pu­ter pro­grammer AKA soft­ware deve­lo­per, you will play a prime role in the designing, instal­la­ti­on, expe­ri­men­ting and main­tai­ning the soft­ware sys­tems. The pro­grams you build will likely assist orga­niz­a­ti­ons offer a bet­ter ser­vice or be more effi­ci­ent. Here are the pha­ses of soft­ware deve­lo­p­ment care­er you should expect to accom­plish in your goal to beco­me a pro com­pu­ter pro­grammer or soft­ware developer:

The Sta­ges of your Soft­ware Deve­lo­p­ment Career

Stage#1: Coder

A coder is typi­cal­ly a hob­by­ist. Some of the respon­si­bi­li­ties you will have to ful­fil in this sta­ge inclu­de lear­ning how to uti­li­ze pro­gramming lan­guage syn­tax, crea­ting small pro­jects yourself and being a good pro­blem solver.

Stage#2: Juni­or Developer

As a juni­or deve­lo­per, you will now start par­ti­ci­pa­ting in the IT mar­ket as a paid expert. Howe­ver, you will have to work clo­se­ly with other pro­fes­sio­nal soft­ware deve­lo­pers who will be gui­ding you on what to do.

As a juni­or deve­lo­per you will requi­re lea­ning how to break issu­es into small and more mana­ge­ab­le pro­jects. You will also start lear­ning how to link vary­ing sys­tems tog­e­ther like lin­king from the ser­ver-side code to a data­ba­se or cli­ent-ser­ver interaction.

Stage#3: Inter­me­dia­te Developer

At this sta­ge you will alrea­dy be a com­pe­tent con­tri­bu­tor and team mem­ber. As an inter­me­dia­te deve­lo­per, you will alrea­dy have lear­ned the way of buil­ding basic sys­tems like web app­li­ca­ti­on. You will howe­ver be requi­red to know how to uti­li­ze pro­per­ly pro­fes­sio­nal too­ling and to be know­led­ge­ab­le about basic sys­tem architecture.

Stage#4: Seni­or Developer

As a seni­or deve­lo­per, you will have to make more com­plex sys­tems uti­li­zing advan­ced pat­terns and methods. In this sta­ge you will alrea­dy be having some advan­ced and spe­cia­li­zed pro­gramming knowledge. 

Being a seni­or deve­lo­per will requi­re you to be know­led­ge­ab­le about refac­to­ring, design pat­terns and code smells, and know­ledge about archi­tec­tu­ral para­digms such as Event Sourcing, Domain Dri­ven design, etc.

Stage#5: Lead Developer 

At this sta­ge your focus will be to offer high-level enligh­ten­ment to your deve­lo­p­ment team. Howe­ver, your prime role as a lead deve­lo­per will be to act as a link bet­ween the deve­lo­p­ment team and other busi­ness-ori­en­ted sec­tions in the organization.

Stage#6: Tech Leader

In this sta­ge your name as an expert is alrea­dy renow­ned in some par­ti­cu­lar loca­ti­ons. As a tech lea­der you will have a spe­ci­fic tar­ge­ted posi­tio­ning or bran­ding as to what you accom­plish well. For instance, your tar­ge­ted posi­tio­ning may be a par­ti­cu­lar pro­gramming lan­guage, front-end deve­lo­p­ment, web secu­ri­ty, or a deve­lo­per mentor. 

Bot­tom Line

In order to be a suc­cess­ful soft­ware deve­lo­per, always make sure you are open and fle­xi­ble for con­ti­nuous deve­lo­p­ment and lear­ning des­pi­te the role you play in your orga­niz­a­ti­on. Stick to this princip­le and be cer­tain you will always be set for advan­ced growth and success. 


web.sta – web-app, tar­get brow­ser is Inter­net Explo­rer 9 & 11

Text­Sys­tem – stan­da­lo­ne desk­top app­li­ca­ti­on, writ­ten in Java/Swing

Inter­me­dia­teLay­er – Cli­ent-Ser­ver app, lin­king web.sta and Text­Sys­tem together. 

web.sta can call Text­Sys­tem via the Inter­me­dia­teLay­er. Inter­me­dia­teLay­er crea­tes an HTTP ser­ver for this pur­po­se and web.sta sim­ply sends GET or POST requests to the local­host. Inter­me­dia­teLay­er pro­ces­ses the request para­me­ters and starts the Text­Sys­tem. The­re is no need for feed­back calls, so the inter­ac­tion sche­me is simp­le and robust enough.


In Citrix envi­ron­ment we can not crea­te several lis­tening sockets on the same IP address and port. It is necessa­ry eit­her to chan­ge the port, or to chan­ge the IP address. But Citrix pro­vi­des a spe­cial mecha­nism for cir­cum­ven­ting this restric­tion, without chan­ging the algo­rithm of the pro­gram. This mecha­nism is cal­led Vir­tu­al IP Loo­p­back. The admi­nis­tra­tor sim­ply con­fi­gu­re necessa­ry app­li­ca­ti­ons in the Citrix con­fi­gu­ra­ti­on panel and the app­li­ca­ti­on that uses local­host for socket con­nec­tions will recei­ve not, but an IP address in the form 127.0.0. <SID + 1>, whe­re SID is the ses­si­on ID of the Win­dows user.

The Pro­blem

All this worked fine under IE9 (and with other brow­sers too) on Win­dows Ser­ver 2008 R2. And then the cli­ents wan­ted some­thing new and Win­dows Ser­ver 2012 R2 appeared with IE11. And the who­le sys­tem stop­ped working. Regard­less of Citrix IE11 set­tings, when spe­ci­fy­ing “local­host” it always tri­es to estab­lish a con­nec­tion to, but nobo­dy lis­tens the­re. After a litt­le rese­arch, we came to the con­clu­si­on that this is a bug in IE11.


If the vir­tua­liz­a­ti­on for local­host does not work out of the Citrix box for IE11, then let’s wri­te it ourselves!

For the­se pur­po­ses, we deci­ded to wri­te a win­dows ser­vice, which will be the simp­lest web ser­ver, lis­ten to and redi­rect requests to the desi­red Inter­me­dia­teLay­er, based on the ses­si­on num­ber of the user. We did not find a simp­le solu­ti­on to get the SID, but we immedia­te­ly found SES­SI­ONNA­ME in the envi­ron­ment varia­bles. In IE via ActiveX we get the envi­ron­ment varia­ble, pass it as a para­me­ter to the HTTP request. In Rou­tingSer­vice by the ses­si­onna­me through wtsapi32.lib we get the ses­si­on num­ber. Then we redi­rect the HTTP request and return the respon­se to IE.

Some­thing went wrong

We began the tes­ting and inte­gra­ti­on of our ser­vice. But not ever­ything went as smooth as we would like.

As it tur­ned out, the name of the ses­si­on can be chan­ged, alt­hough we did not under­stand in what con­di­ti­ons it hap­pens. But often it hap­pen­ed that the ses­si­on name chan­ged, and IE11 only knows the initi­al value of the envi­ron­ment varia­ble. And per­sist­ent­ly pas­ses this value to the RoutingService.

What is in the registry?

It is necessa­ry to find ano­t­her way to get the ses­si­onna­me. We have loo­ked for infor­ma­ti­on about ses­si­ons in the regis­try and tha­t’s what they found: in HKEY_CURRENT_USER \ Vola­ti­le Envi­ron­ment we can get a list of ses­si­ons of the cur­rent user.

If the user ses­si­on is one, then ever­ything is fine, we can read and use it. And if the­re are a lot of ses­si­ons for one user, then we need to somehow deter­mi­ne which ses­si­on we are in. We could not come up with anything bet­ter than matching the path to the tem­pora­ry files folder.

Here is an example:

In IE, we get the cur­rent path to TEMP using ActiveX Scripting.FileSystemObject.

This way we mana­ged to get the name of our ses­si­on. But tha­t’s not all. The value of the keys under the Vola­ti­le Envi­ron­ment is, in fact, the SID is. That is, we can immedia­te­ly get the necessa­ry IP address in Java­Script and send a request to it.

Shall we sim­pli­fy it? 

Final­ly we can get the SID and estab­lish a con­nec­tion direct­ly, without using Rou­tingSer­vice. But the solu­ti­on still does not look beau­ti­ful. Stu­dy­ing the Inter­net show­ed that the pro­blem exists, but the solu­ti­on to this pro­blem is not descri­bed any­whe­re. And the Micro­soft keeps silence as well. 

We hope someo­ne with this spe­ci­fic pro­blem can bene­fit from our experience.

Soft­ware Qua­li­ty Assuran­ce (also abbre­via­ted as SQA), can be defi­ned as a sys­te­ma­tic pro­cess which ensu­res that the deve­lo­ped soft­ware meets and com­plies with the stan­dar­di­zed qua­li­ty spe­ci­fi­ca­ti­ons. It keen­ly checks the adhe­rence to the soft­ware pro­duct stan­dards, pro­ce­du­res and pro­ces­ses all throughout the soft­ware deve­lo­p­ment life cycle and also the test cycle. The eva­lua­ti­on is done through pro­duct eva­lua­ti­on, pro­cess moni­to­ring, pro­ject manage­ment, and more. Read more

With ever­ything going digi­tal a Docu­ment Manage­ment Sys­tems, also known as DMS, ensu­res that you are able to easi­ly edit, mana­ge and orga­ni­ze your docu­ments. Moreo­ver, you can also keep records and track any chan­ges made to docu­ments. In this post, we will focus on dif­fe­rent com­pon­ents of DMS in order to under­stand its wide scope. This will give you an idea about various ser­vices offe­red by com­pa­nies deve­lo­ping DMS sys­tems, Intech­core being one of them. Read more

IT out­sour­cing has pro­ven to be a pro­spe­rous stra­te­gy that has been gai­ning popu­la­ri­ty year after year. In today’s com­pe­ti­ti­ve busi­ness are­na, com­pa­nies are always try­ing to find ways to cut cos­ts and incre­a­se over­all pro­fi­ta­bi­li­ty. One of the best ways to achie­ve that is IT out­sour­cing. While it is true that you can out­sour­ce a num­ber of depart­ments from help sup­port to mer­chan­di­sing, IT out­sour­cing has pro­ven to be very lucra­ti­ve, as you can find a lot of IT pro­fes­sio­nals resi­ding in nati­ons whe­re the hour­ly rates are very low. If you want to know more about spe­ci­fic advan­ta­ges of IT out­sour­cing, then you have come to the right place, as this arti­cle is going to cover the sub­ject. Read more
