3. Abstract With an increased demand for reliable and performant infrastructures designed to serve critical systems, the terms scalability and high availability couldn’t be more popular. While handling increased system load is a common concern, decreasing downtime and eliminating single points of failure are just as important. High availability is a quality of infrastructure design at scale that addresses these latter considerations.

4. Overview High availability (HA) is a term that describes a web site or application with maximum potential uptime and accessibility for the content stored on that. While a more basic system  are be  capable  serve content to  an occasional  or medium number of users, it should include one point of failure. going to It is useful for the businesses application and productivity which often take place in mission-critical atmosphere. By deploying HA system in your enterprise, you can make your servers and operations more strong, consistent, and resilient.

5. Elements Required for Creation of HAS To create HAS there must be three elements that is required Redundancy Monitoring Failover Redundancy: In computing, redundancy approach that there are multiple components that can perform the equal project. This eliminates the unmatched factor of failure problem with the aid of  permitting  a  second  server to take over a  project  if  the primary  one  is going  down or  will become disabled.  Monitoring: The system needs to be able to monitor itself for failure. This means that there are regular checks to ensure that all components are working properly. Failover: Failover is the process by which a secondary component becomes primary when monitoring reveals that a primary component has failed.

6. Requirement of High Availability is Important! When putting in robust production systems, minimizing downtime and service interruptions is often a excessive priority. Regardless of how dependable your systems and software are, issues can arise t hat could  convey  down your  packages  or your servers. Implementing  high  availability  to your  infrastructure is a useful  method  to  lessen  the  effect  of these  sorts of  events. Highly available systems can recover from server or thing failure automatically.

7. Components Required for High Availability System Several components that must be carefully taken Environment: If all your  servers are  positioned  in the  same  geographical environmental  condition  together with  an earthquake or flooding  your entire machine down. area, an should  take Hardware: Servers should be resilient to strength outages and hardware failures, together with hard disks and network interfaces Software: Whole  software  stack,  consisting of  the operating  device  and the  utility  itself,  ought to be prepared for handling sudden failure th at would  potentially  require to restart machine. HAProxy a  common  desire  for load balancing, as  it can  manage  load balancing at  more than one  layers, and for of servers, which includes database servers. (High Availability Proxy) is different  forms

8. Features & Benefits of HAS Easy to Maintain Downtime is the not the only issue your business face. You have to maintain and upgrade your hardware and software which are costly. Maximum Flexibility Only High Availability solutions can give you this degree of flexibility. A partial failover mode of a server lets you carry out communications by using different interfaces. Real-Time Backups It ensures that the recovery copy is accurate to within a very short time frame. Real-time backup works by automatically updating the latest backup version of a file as soon as it is modified, ensuring recovery copies are accurate to within a few minutes. Hassle-Free Implementation High availability system can be implemented with minimal hassle. The entire system can be built and tested separately without disrupting business operations. When it is ready, migration can be scheduled at a timing least affecting operations.

9. Conclusion High availability is most important subset of reliability engineering, and more focused towards assuring that a system or component has a high level of operational performance in a given period of time. At a first glance, its implementation might seem quite complex; however, it can bring tremendous advantages for systems that require increased reliability.
