Best Practices for SaaS Software Testing & QA

Corporates come across immense challenge when they migrate from traditional development platform to SaaS based software deployment. The constraints can be language for different regions, performance issues etc. When we think about testing for SaaS based software, we primarily emphasize on three things; a> Scalability b> Released Processes and c> Architecture.

SaaS based software testing can be categorized in the following areas.

a> Functional Testing: As like any other platform, you have to make sure that the functionality of the software is working properly. The following test can be conducted to confirm this ie.

* Manual test scripts
* Exploratory charters
* Checklists
* End-to-end scenarios

You can also use some type of tools like Selenium to automate regression test.

Multi Platform support: You can use both physical and virtual machines to test on multi platform like Windows, Mac and Linux and also on the browsers like IE, Firefox, Chrome and Safari.

Security: You have to keep an eye of your SaaS software from any external threat. In order to do this, you have to plug the gap so that cross-site scripting and other security loopholes can be avoided.

Load and Stress Test: It may be possible that your software is used by large number of users simultaneously. So, it is crucial that you conduct some type of Stress or Load test to simulate real life scenario. You can try Jmeter as a stress tool.

Disaster Recovery and Rollback: If system is down due to any power outage or other disaster, it should be brought up as soon as possible. Additionally, there has to be rollback option to the last known good version of the data.

Language: Since, Saas platform is used by different clients from different locations, you have to make sure that it supports the international language.

Remote Usage: Since, clients from different locations can use the SaaS platform, it is important that those people can access to the system with good response time. You can use some kind of emulators to conduct the test. But, the best thing to create real life situation is to use the collaborators. They can conduct the test and report the results.


What is Software Escrow

What is Software Escrow:

When you arrange for your software to be written by an external developer, you and the developer can agree that a copy of the source code will be given to a neutral third party – an escrow agent. The agreement should mention that under what terms and condition the source code is going to be released.

When do you need Escrow account:

When you contract out your software to be written by any outside developer, you need to make several decisions. One of the crucial part is what the developer will do in terms of source code during delivery of the software. You may need the source code down the road to make necessary changes or any bug fixes. What is going to happen if the outsourced company goes out of business for bankruptcies or the developer may die. On the contrary, the developer may want to retain the software or may ask you extra money to release the source code. That’s where the role of the escrow account arises. You can request the company or developer to retain the source code with a third party agency, the escrow account.

What is Software Source Code:

Source code is a collection of statements written in human readable programming language. Programmer write source code to instruct the computer about the type of action it will take. The source code that builds the program is kept in a text file or database. When you purchase a program, usually, you receive the executable code and that is a machine language format. In order to change the software or any other fixing of bugs, you need the source code.

What is Software Escrow agreement:

Choosing the right Software Escrow services is the next major step. Although, you can do a google search to find many listing, but, it is equally important to know their pricing, how long they are into Software Escrow the type of services they actually offer and the number of Escrow actually claimed. Also, you can check any negative feedback about those companies through Better Business Bureau.There are three types of Escrow agreement Plan, namely, Single user Plan (SUP), Multi User Plan (MUP), Investor Security Plan(ISP).

* SUP: The single user plan is for software that will only be used by one business. Usually, it is going to be highly customized software and the cost is also very high. There are three signatories for this agreement, suppliers, the licensed user, and the software escrow agent.
* MUP: In this type of plan, the software is sold to many different users or licensees. This is suitable for packaged software. There are two signatories, the escrow agent, and the software supplier.
* ISP: Investors Security Plan is to protect software investors from fraud or scams,as huge sums of money are often involved with software development. In this case, investors, developers, and the escrow agent need to sign the agreement

What is the cost of software Escrow :

* In most cases, software escrow companies will charge both the beneficiary and the developer for getting their services. In this way, the cost is usually diversified so that the load is not going to be very high for every participant in this contract.
* If there is more than one beneficiary, everybody has to pay the fee. Generally, the fee is the same that they would have paid in case there is one beneficiary.
* If there is more than one developer, all of them have to pay the fee to the Escrow account. Escrow agreement does not only protect beneficiary, it also protects the developer. Most of the software Escrow services provide yearly and renewal rate

What are the procedures for Software Escrow:

* Agreement: The Escrow agreement is done among licensor as depositor, his licensee as beneficiary, and an escrow agent.
* Deposit: The licensor, as per the escrow agreement, delivers the asset to be escrowed, and change the ownership of it, to the escrow agent. The asset contains a copy of a source code and a copy of an object code, documents such as design, specification, flow chart, manual, maintenance material etc.
* Custody: The escrowed agent puts the asset in a sealed container. Once it is sealed, the agent or other person is not allowed to access it.
* Delivery: If any incident mentioned in the agreement occurs, like lisensor goes bankrupt, no maintenance for a certain period of time, the licensor’s closing his place of business, etc. the agent delivers the asset to the licensee on request. If the licensor raises an objection for delivery, he can hold the asset till the matter is settled between the parties.
* Fees: The licensor usually pays the fees. licensee is allowed to pay it to secure the continuance of custody.

Dedicated Hosting vs. Cloud Computing Infrastructure

There are various choices for web hosting plan for businesses. The best choice for web hosting entirely depends on how the business is set up. For the established businesses dedicated hosting seems to be the ideal choice. However, for the startups, cloud hosting is a better choice.

Who should use Cloud Computing Infrastructure?

Cloud hosting infrastructure relies on its web-based technology, and is ideal for those lacking resources to invest heavily into your hosting. It is anticipated that cloud computing must experience several significant growth spurts during the next few years. It’s probably cloud hosting what your business needs.

Who should use Dedicated Hosting?

Dedicated server is meant for established businesses that doesn’t wanna invest in any hardware or infrastructure or the additional space that comes with having your servers on-site.

A dedicated hosting is dedicated to the business’s websites, applications and platforms. The business will enjoy the full and complete power and bandwidth of your dedicated servers, and nothing should affect server performance, unless you choose to let it.

Key Differences

Hardware requirements

One of the major drawbacks with cloud hosting is the lack of access to the operating system and/or hardware. In case you need to fine tune the software/hardware stack then dedicated server is the best solution.


This is one of the most considerable advantages cloud hosting, scaling up beyond a single server is notoriously difficult on a dedicated server setup -load balancing, maintenance session across different machines and such other issues make scaling quite difficult.

Comparatively, Cloud hosting allows easier scaling by spinning up more instances as required. The instance can be programatically spun up and destroyed as required meaning the application can handle all the scaling without the need for intervention. Further, to write custom code, third party products such as RightScale can sit on top of a cloud hosting instances and implementing all the scaling automatically.

Requirement for OS/Hardware

One of the major shortcoming with cloud hosting is the lack of access to the operating system and/or hardware. In case you wanna upgrade or fine-tune a software/hardware stack then dedicated hosting is the only way to go.


Dedicated hosting offers price advantage for small installations. The single low-spec (2GB RAM, 160 GB Storage, 2Ghz single-core CPU) dedicated server will cost about $130 per month for dedicated hosting. This actually comes with a huge amount of bandwidth (2TB per month on Server Beach for example). Contrastingly, the cloud hosts charge a little less for the hardware. However, the charges for bandwidth with cloud hosts are much more expensive approximately $0.11 – $0.14 per GB. In case the visitors to your site require lot of bandwidth that means extra charge.


A cloud server is less secure than the dedicated host. In case, your instance is a part of a cluster of machines normally that will be less secure than an isolated machine, which has fewer connections. It needs to be considered that cloud hosts will have a dedicated security team to patch the OS when necessary and implement security best practices which will often not be fully adhered to if you have to manage the security of a dedicated host. The greatest vulnerabilities are usually at the application level that is independent of the platform.

Ease of use

Cloud servers are easier to handle and use than the dedicated servers. Further, servers can be added via control panel and all OS patching can be easily managed.


Cloud servers have a built in failover, which ensure that you don’t have a hardware/server failure. It must be remembered that a cloud host is a cluster of servers that you can share with other users, severe slowdowns can occur from the other users running long running queries on the cluster.

Top 10 Reasons to Choose Cheap Dedicated Web Hosting Over Shared Web Hosting

Success of any website to large extent depends on its Web host. Some of the most common choices for web hosting include shared web hosting and dedicated web hosting. The basic difference between web hosting accounts is that either the site is hosted in its own server or shared with other Web sites. To choose a Web host you need to look into the several aspects of site’s technology, storage, and bandwidth requirements.

Typically for a busy site with large volume of traffic choose dedicated hosting option form their Web host. Dedicated hosting would mean it is your only site residing on the server and you are not sharing your IP address with any other site. Website owners avoid dedicated hosting and opt for shared hosting primarily due to the expenses. Even a small medium enterprise has to think twice before investing in dedicated hosting. However, there are cheap dedicated web hosting providers who can fit low budgets. Moreover, even if dedicated hosting costs more, the price is worth the feature and benefits offered with it. We provide 10 valid reasons why to choose cheap dedicated hosting over shared web hosting.

1. Faster response

Since the dedicated servers are solely dedicated to your website , the response time will be faster. Visitors will have too much faster response, as there are smaller queues to wait. Slow server response hampers the promotion of your site by frustrating visitors. In some cases, the pages may timeout and never load. This is especially not expected if that happens when search engine spiders crawls. Find out the IP address of the server you wanna share. You can use NetMechanic’s Server Check tool to monitor the server and monitor its response time.

2. Easier to setup

For server with dedicated IP address it’s easier to set up the server to handle anonymous FTP and SSL encryption. This is not impossible with shared hosting, but it is more difficult. Some shared web hosting providers don’t offer SSL encryption or charge a premium for it.

3. Full Control

Unlike shared hosting, in dedicated hosting the functioning of your website is not hindered by other’s activities. You are free to install any application and you can also carry out the scripts testing as frequently as you want. With dedicated hosting you have much more freedom and running your website entirely depends on you. Moreover, you will have the authority to customise the hardware and softwares installed on your server. These privileges are not provided under shared hosting.

4. Server Crashes Regularly

In shared hosting factor to server crashes are more prevalent. In face there are certain scripts that can overload a server’s resources. The web hosting monitor doesn’t monitor the server’s activity and those poorly written CGI scripts cause more hassle than relief. It is vital for host provider to monitor the server regularly to prevent server from crashes and to protect your site from being affected.

5. Sharing Same IP

One of the main concerns with shared hosting is having the same IP address. When other sites in the server with same IP address is blacklisted for unethical activities, spamming or generating illegal script. When you share the same server, you have the same IP address. If any of the websites sharing the server is blacklisted those sharing the same IP will also suffer, being banned by search engine overall. You might be the victim of crime that you haven’t committed.

Having the same IP address in shared hosting is the main concern when other sites in the server is actually being blacklisted for unethical activities such as spamming or generating illegal script.

6. Bandwidth restriction

In shared web hosting each website has a limit for their bandwidth, which hinders the access. On the contrary dedicated web hosting allows users to consume the full bandwidth. The entire bandwidth available on the server lies at your disposal.

7. No bandwidth penalty

Shared hosting accounts normally offers a certain amount of bandwidth per month to each site on the server. Sites that go over their allotment get charged extra. Dedicated hosting generally has no restrictions since it is assumed that you need a lot of bandwidth for your own server.

8. Security

Having a dedicated server is in fact more secured compared to shared hosting. This is a dedicated server with its own firewall. The information stored in dedicated server is less vulnerable to attacks by hackers or any materials from your site will not be a problem, if you have a lot of daily visitors performing such activity.

9. Better Performance

Dedicated hosting means that you alone are hosted in that server. The response time of the server to requested files is much faster as compared to shared hosting. The visitors browsing your website will feel happy as your pages will appear on their browser fast enough to satisfy them. Fast loading time will always brighten the day.

10. Higher Cost

In case of dedicated hosting you have to monitor and regulate the server yourself, the cost incurred by you will be greater. You need to invest on hardware and security, and carry out maintenance checks regularly. However, the benefits and feature are worth the cost.
