High Availability & Site Reliability

High availability relates to a system that is maintained at an agreed upon performance and operational standard. Often the agreed, or guaranteed, performance is for the systems ‘uptime’ and covers a certain period of time.

If you have systems that are required to be available for regular use, such as sales systems, customer databases and submission systems the high availability and the site reliability can be used to keep your systems functioning when you need them the most. In order to make this happen you’ll need people in place to monitor and manage the systems required.

Site reliability determines what processes and programs can be launched and at what times. It uses a mathematical formula to determine when and if programs and other infrastructure should be launched. Site reliability is what will keep your systems operational when performing upgrades, or anything that needs to be launched, and to do so safely without affecting any other systems.

Often upgrades and new applications will need to be uploaded and launched on your systems, with these two working in conjunction it can make sure that your systems work safely together and do not fail.

 

Evaluate & Test IT Infrastructure

Evaluate and test IT infrastructure is when a system and its components are tested to see if they are suitable based on their specifications and requirements. By evaluating the results, it can be determined if the infrastructure meets the predetermined specifications.

Completing this is necessary in order to know which applications and components will work the best for your system and its needs. These tests are done in order to reduce overall risk of launching new products into your current system.

 

Application High Availability

Knowing of your system will perform at scale is required for successful launching. By completing an application with high availability, it can be determined if further scaling will be a success or a fail. Only with the proper testing and reports can an accurate decision be made.

When completing this test, we will be looking for system load, decreased downtime, and points of failure. Application high availability means that the installation of your application will not affect your systems in a negative manner.

 

Load Balancing

Load balancing is creating pathways so that your system is not overloaded one way or another. There are many ways to accomplish this, but the main way is to set up physical devices, or virtual instances running on specialised hardware, to send information to the server that is the most available at that time.

This means that your systems will keep operating at peak times, and that it will not be overloaded by too many queries being made at one time to one server. It’s a way of sharing the load and making everything operate as a whole unit.

 

Design Build

Design build is the way that your system is structured, so high availability can be maintained even in the loss of one element. We design systems, so you're able to take advantage of the increased performance it offers. Your systems will be protected from unforeseen failures as all the other parts will be able to make up for the loss of one.

 

Enhance on High Availability & Fault Tolerance

Fault tolerance is when specialised hardware is deployed to detect faults in separate components and keep mirrored systems running in synchronicity. The result of using fault tolerance can eliminate server down time.

The best thing about this system is that you’ll not lose any data in the event of a failure, as the systems are working together. If there is a failure the mirrored system can complete the transaction.
