How to keep apps 99.99% high-available and high-performing

Featured article by Elsa Kairo

In this technological era, there is a high chance of system interruptions that results in the inaccessibility of the apps, so the availability and performance of apps are of high priority among the users. When the availability of apps becomes extremely difficult, the companies have to adopt some approaches to solve this problem and provide highly available apps as well as high performance.

High Availability (HA) measures are the arrangements in the system, due to which the availability of service would still exist even if the main server shut down. The businesses that require apps that are highly available all the time include e-commerce websites like Amazon, Alibaba, B2C and B2B portals. Now, the question is how to achieve high availability and high performance.

To answer this question, there are certain strategies to keep the apps accessible 24/7.

How to achieve 99.99 % availability and performance? 

Make apps available geographically

The apps will be highly accessible if they are available anytime at any place regardless of the geographical location. Also, there should be apps available even in the situation of natural disasters e.g. earthquakes, tsunamis, thunderstorms by applying multiple application servers.

Implementing strategies for network load balancing

There should be a strategy for fast transmission of data on different terminals. When large amounts of data are transmitted through one terminal then there would be overloading of the data transferring on the network. So, you can ensure provide highly available connection by offering multiple servers to transmit data.

Structural design for resiliency

There are three structural designs available to provide resiliency. Two of the most important are given below.Disaster recovery strategies are designed for saving confidential data that prove a real asset for the company. The disaster recovery strategy works by setting specific rules and policies.

Availability design goal

The company accepts that the minimum number of system breakdowns would require manual efforts from experts. The company requires some time to recover from the system breakdowns but ensures that no permanent damage is made and no data is lost.

The high available apps should also have high-performing capability due to which you can easily access the apps. Such as the apps should be:

User-friendly

The apps that are highly available to the client should be easily understandable by the client. For example, when apps are not user-friendly, they are useless whether they are highly available or not.

Be cost-effective and time-effective for the users

The apps would perform high when they are accessible fast and with very little to no cost to get access to.
