Login VSI is the industry standard in VDI performance testing. The load-testing and active monitoring solutions of Login VSI are all based on our industry standard, and patented, Virtual User technology. The Login VSI Virtual User technology consists of a proven methodology, industry standard user workloads, and the indexes VSImax (for scalability), and VSIbase (for performance). Login VSI is used by both vendors and enterprises to build and manage centralized desktop environments with superior performance and availability. Login VSI provides business value in many scenarios:
Test L1TF Mitigations in VDI
Today Intel published publicly about a series of new security vulnerabilities named L1 Terminal Fault (L1TF). There are three applications of L1TF speculative execution side-channel cache timing vulnerabilities. To learn more about the speculative execution side-channel method called L1 Terminal Fault (L1TF), and the way the vulnerabilities work, please check out this very clear video by Intel.
In virtual desktop production environments, changes cause the most problems. These can be planned changes such as new versions of business applications (like SAP or EPIC), regular new builds of Windows 10 or standard weekly updates (e.g. “patch Tuesday”), as well as unplanned changes such as automatic updates (think of security software). However, just normal daily use can also cause a gradual deterioration of desktop and application performance due to the pollution of storage and other devices.
Application Performance and Availability
In virtual desktop production environments, the end-user experience is always the primary concern. Login VSI Enterprise Edition helps to safeguard the performance and availability of your critical business applications, whether they run in your own datacenter (using VDI or server-based computing) or from elsewhere (using DaaS, IaaS or SaaS providers).
Remote User Testing
Your virtual desktop users work from different locations - and while you strive to deliver the best possible user experience, there are many external factors that can have a negative impact. For example, the distance to the datacenter, the speed and quality of the internet connection, as well as other bottlenecks along the way, can produce support tickets even though the desktop environment in your data center is running smoothly.
Disaster Recovery Planning
To protect and maintain business continuity is key for any organization. To cope with all (IT related) changes that may impact application availability and therefore disturb business operations, most large organizations have implemented comprehensive and structured change management programs. Programs including pre- and post-testing planned changes with realistic user numbers, and pro-active detection of slowdown caused by unplanned changes or gradual deterioration.
Building Virtual Desktop Infrastructures
The load testing capability of Login VSI is a necessary tool to build well-performing virtual desktop infrastructures. Login VSI is used in both the design and build phases for vendor benchmarking, sizing/scaling and pre-production load and stress testing.
While the use of on-premise VDI is still growing, there is also a strong move towards cloud-based solutions for desktops and/or applications. Industry analysts especially recommend cloud-based solutions, like DaaS and SaaS, for environments where most end-users have very short term engagements, and where the applications used are relatively light weight. Their expectation is that both VDI and DaaS have their benefits for different types of users, and will therefore be used side-by-side in most organizations.
Meltdown and Spectre
Organizations running business critical applications in centralized desktop environments are urgently looking for help to objectively assess the potential performance impact of all Meltdown and Spectre patches coming their way.
Login VSI is the industry standard for VDI and SBC performance & scalability testing and is a great alternative for Loadrunner load-testing. Login VSI is not only easier to use, easier to understand, and the industry standard for VDI testing, it is also just a very cost-effective alternative for LoadRunner.
