Performance and Security

And Security

Success or failure of a project is determined by the ability of the software system to scale well and to adequately satisfy the transaction volume without unacceptable delays. With companies moving towards component based Service Oriented Architectures and the many layers that the transaction has to pass through, performance has become a key aspect of all software projects. Given the complexities of modern architecture, CPU power and memory capacity alone does not ensure high performance metrics. The architecture, design and implementation has to be sound to ensure that the application is scalable. Our performance improvements service takes a comprehensive look at the architecture, design, implementation and deployment of an application to ensure that the users do not experience unacceptable delays. We assist corporations with setting performance goals and work together to achieve these goals. We have methodologies and best practices in place to review the performance issue in a methodical way in an effort to eliminate performance bottlenecks. We also employ performance testing tools, such as Mercury Load Runner, to simulate the target load. We use our performance tracking and analysis components, and third party software such as Wily, Team Quest and IBM Heap Analysis Tool, to gather details and tabulate the results to recognize resource usage trends and to predict and address failure points.

We help corporations identify performance goals and work together to achieve these goals.

In the interconnected electronic world, one key aspect of every software system is security. Every software system must ensure that the user is authenticated and authorized to perform the requested transaction. Research shows that even a medium sized corporation has over 100 applications and over 10 different languages in use. As a result, it is a major challenge for corporations to ensure a uniform method to enforce security policies and enable single sign-on options. Jarus Health has assisted many organizations in enabling the following:

  • Single sign-on : Irrespective of whether the application is J2EE or Microsoft .NET or legacy, enable single sign-on to authenticate the user once and permit access uniformly to all applications that the user is entitled to access.
  • Role based security: Centralize security policies by defining user roles. Each role permits or denies access to network resources (i.e. web applications, URLs) and each user or group is assigned roles based on their access credentials. Using role-based security, we are able to centralize a very fine access control by the use of security filters. This not only improves security, but centralizing security ensures simplified application development.
  • User or Partner self-administration: Depending on the customer’s situation, we help our customers in providing self-administration for users and business partners. Using these features, users are able to change their password periodically, reset passwords, or perform other routine administration functions without increasing the load on customer service.
  • Audit and Reporting: Centralized security modules track each transaction and records who is doing what and when. By using this information, it becomes possible to audit for unusual activities and report any issues.
