Seven Steps to Prevent Downtime

Downtime is when your website is offline due to a mistake, scheduled maintenance, or other reasons. Everyone in this industry is concerned about downtime since it causes financial and reputational damage, and every effort should be made to prevent it. For example, several months ago, Delta encountered an IT outage that cost them more than $150 million and reduced their profit margins by up to 3%. Customers were stranded for hours, 2300 flights were cancelled, and Delta had to pay for thousands of hotel and travel vouchers to compensate for the extended outage – despite the strong probability that the incident resulted in the irreversible loss of some customers.

With apps and services from even multi-million dollar businesses, downtime can occur anytime, and a single prolonged issue can cost a company hundreds of millions of dollars. But if you follow these measures, you can mainly prevent situations like this:

1. Adopt An Architecture Of Microservices: 

Historically, programs were constructed monolithically or by creating the entire application as a single unit. Microservices architectures are gaining in popularity today. They entail developing, testing, and deploying an application in independent subcomponents. Because the application’s components are isolated from each other, maintenance is much simplified. Therefore, if one part fails, it may be targeted and repaired independently without affecting other features. If something goes wrong in a monolithic program, the entire application will experience downtime, and it will be impossible to determine precisely what went wrong. Installing microservices makes your application more resistant to an outage and is the first step toward attaining high availability. However, be mindful that microservices designs introduce significantly more complexity and increase the amount of monitoring data collected. Therefore it is essential to be able to correlate alerts and suppress non-actionable warnings to reduce overall noise.

2. Make Releases More Rapid And Frequent:

The most significant advantage of a microservices architecture is that it enables faster releases—multiple times per day for web applications and every two weeks for mobile applications. The previous norm required significant releases approximately every three months, with inevitable downtime for each release. With the contemporary strategy, releases are dispersed. Only bits of the program are deployed in the background at any given moment, so the platform is always operational. This decreases the danger of downtime and makes you more competitive by increasing your release velocity, allowing you to deliver more innovative features and value.

3. Availability Is A Matter Of Quality:

Quality and accessibility go hand in hand. Numerous firms are so blind to the significance of quality assurance that they put it off until the last minute. To prevent defective software, the QA team must be involved as early as feasible in the development phase and throughout the release lifecycle. QA should concentrate its efforts on testing strategy and automation. Compared to a manual approach, a test automation framework can minimize errors while drastically cutting expenses and saving time. In addition, testers must be actively involved in the requirements process to guide development on the right path. By helping to ensure that the development team builds correctly from the outset, the business will incur less technical debt in the future. Continuous improvement is the purpose of quality assurance, and your incentives should reflect this.

4. Have A Plan For Disaster Recovery:

When essential app services are interrupted, it is a catastrophe. In these circumstances, a solid disaster recovery plan is required. With the majority of enterprises utilizing hybrid architectures that include both public and private cloud infrastructure, it is essential to have redundancy across your servers and to create backups with several providers. Virtualization can be handy for creating an image backup of an existing physical server, and containerization can be even more helpful because the image backups are much lighter and use less space. These strategies ensure that your data is accessible even during a catastrophic event. Further, you must automate your backup process from beginning to end, so it does not rely on an administrator’s approval, mainly if they are unavailable. Additionally, automation enables your DevOps team to test the disaster recovery strategy and prepare for any potential crisis.

5. Utilize Change Management:

Ensure established frameworks, such as ITIL, are used for ITSM change management. Changes are beneficial to IT services, without which there would be no advancement; nonetheless, all differences must be documented. By measuring and publishing change success rates, determine whether teams have a poor change success rate. iVedha is an excellent ITSM tool for increasing visibility and control over change management. It enables rapid, efficient, and little disruptive modifications to IT services.

6. Use An Incident Management Tool:

When inevitable downtime occurs, it is crucial to tell the appropriate team members immediately. But frequently, teams receive too many notifications, causing them to overlook the critical ones, impacting the mean time to resolution (MTTR). During an outage, an incident management tool helps organize and group alerts from various monitoring systems will prove crucial. It suppresses non-actionable warnings based on quickly established rules, aggregates related actionable signals into incidents, and guarantees that only high-priority events trigger a message to the appropriate persons with the proper context. In addition, iVedha’s connections with your existing monitoring, ticketing, and collaboration tools enable your team to swiftly troubleshoot and resolve events so that your application is up and operating as much as possible.

7. Deliberately Induce Failures:

Planned failure guarantees that your staff is always ready to address any outage. Netflix is well-known for using this strategy. Chaos Monkey is a script that runs continuously in the background and randomly terminates server instances. This enables the team always to be prepared for server outages while servicing consumers without interruption.

Take Action to Keep Downtime Low

Focusing on the people, procedures, and tools that comprise your DevOps team will bring it close to perfection, despite the impossibility of achieving perfection. There is no silver bullet that can remove all of your downtime concerns, but if you follow these steps, you’ll be able to design more reliable apps and gain and maintain your consumers’ confidence and loyalty.
