The concept of High Availability Infrastructure was only confined to the regular business hours at brick and mortar stores prior to the advent of internet, e-commerce, and online services.<\/p>\n

Only as long as the doors were open and the lights were on were the services offered. That\u2019s the high availability<\/a> system of the pre-Internet age.<\/p>\n

But the consumer mindset has changed in the digital age.<\/p>\n

Users expect that Internet services will be available constantly. Regardless of time zone, business hours, or even holidays, online services are expected to be up and running.<\/p>\n

Your IT infrastructure can function normally even if some of its components fail thanks to high availability.<\/p>\n

High availability is crucial for mission-critical systems since a service disruption could have a negative impact on the business, leading in extra costs or financial losses.<\/p>\n

High availability assures that the IT team has taken all necessary efforts to ensure business continuity, even though it does not completely eliminate the chance of service disruption.<\/p>\n

In this article, we will discuss the practices of high availability.<\/p>\n

MAINTAIN MULTIPLE DATA CENTERS\/CLOUD REGIONS<\/strong><\/h2>\n

It’s important to note that you can’t just choose one data center or cloud region. You need multiple locations, depending on your business needs and the applications you are running.<\/p>\n

If you’re running a large enterprise application, it may make sense to have multiple data centers in different parts of the world so that if one location experiences a catastrophe (like an earthquake), other sites can continue running without interruption.<\/p>\n

A similar approach is taken when choosing what type of infrastructure platform should be used for high availability: by having multiple platforms available at any given time, users will be able to access their applications regardless of what happens elsewhere.<\/p>\n

This approach also reduces risk because each platform will be independently managed by IT Services<\/a> staff who know how best to handle its particular needs\u2014which means there’s less chance of downtime affecting critical systems downstream (e-commerce sites being unable to accept orders).<\/p>\n

Continuously monitor your infrastructure<\/strong><\/h2>\n

Monitoring your infrastructure is essential to high availability.<\/p>\n

The first step toward a successful high availability infrastructure is monitoring, which should be continuous and automated.<\/p>\n

Monitoring should also include other aspects of how your application runs: what results do we get from our tests? Are they consistent with what we expect? How often do we fail at certain parts of our codebase (and why)?<\/p>\n

These questions help us understand how well our tests are working as part of an overall picture of whether or not our system is working properly<\/p>\n

Manage Your Uptime with an SLA<\/strong><\/h2>\n

An SLA is a contract between you and your IT service provider<\/a> that defines how long they will be available to respond to requests, including the ability to restore services after an outage.<\/p>\n

The language of an SLA should be clear and concise; it should include the specific types of services being provided, how long each type can be down for (e.g., one hour), what happens if something goes wrong with that service during its downtime window (e.g., no one will be able to access mail), and so on.<\/p>\n

 <\/p>\n

Validate Your Backups with Quick Recovery and Disaster Recovery Testing<\/strong><\/h2>\n

If you want to be sure that your backups and restore processes are working as expected, it’s important to test them regularly.<\/p>\n
