Any developer would hope for zero downtime for their application, but how achievable is this? Our latest white paper examines a number of ways you can work with your hosting provider to influence the uptime of your cloud-hosted applications and the trade-offs for each option.
Do all your organisation's applications need to be working 100% of the time, or just the key ones? Forrester Research suggests that nearly 75% of all applications are deemed mission or business critical. Having systems down can lead to poor service, unhappy customers and staff and ultimately a damaged brand. When Amazon’s Simple Storage Service S3 went down it took almost 150,000 websites down with it! This led to a great many disgruntled companies - even large sites such as Business Insider and Slack went down or experienced issues with services.
As we know, zero downtime is almost impossible to attain without breaking the bank. For every small increase in availability, there will be a corresponding increase in costs. When planning for high application uptime, there are many choices and compromises to be made. As a result it's essential to understand what amount of downtime is acceptable to your organisation and at what cost.
Zero Downtime and Acts of God
It is also important to consider factors that are out of your organisation's control, such as 'acts of god' or environmental constraints. Your organisation, or even your hosted applications, might be in a part of the world where there is a higher risk of natural disasters, which is where off site cloud backup and disaster recovery is key.
Inside Our Guide to Application Uptime
How do you minimise the risk of downtime? Our new guide is designed to help you safeguard your application uptime. Inside, we will break down how your organisation can ensure high availability in 10 steps:
1. The true cost of uptime: Do you need to recover in an hour, a day or a week? And does this differ between systems?
2. Ensuring application uptime in the cloud: Data centre uptime is the starting point for most predictions of application uptime.
3. Single points of failure: Single points of failure can take many forms and may or may not be under your direct control.
4. Scalability: Even if your applications are up, any inability to cope with increases in demand can lead to unavailability for some users.
5. Application architecture: If your application hasn’t been developed to utilise redundant or scalable resources, they won't be effective in improving its uptime and availability.
6. Application performance: Even when everything is within capacity, application performance still has the potential to disrupt you.
7. Business continuity and disaster recovery: Not all threats to application availability can be prevented. How will you maintain availability in the case of a fire or a burglary?
8. Service Level Agreement: The SLA between your provider and you plays a central role in your uptime strategy.
9. Application security: The threat from cyber-attacks and DDoS is ever growing and evolving.
10. Measurement and monitoring: There is little point investing in improved application availability if you are not monitoring and measuring it too.
Application availability is a complex issue, the product of many factors and choices. Download our latest guide to gain crucial insight into the importance of and the options for maximising uptime in the cloud.
