New Release: The Gorilla Guide® To… High Availability for Business-Critical Applications

I worked for one professional company that took about 48 hours to recover from a disaster—an event very detrimental to our business. The company made a subsequent move to the cloud to prevent a repeat of the downtime. Of course, cloud services can go down too, as Netflix discovered on Christmas Eve one year because it depended on a single AWS region for many of its viewers.

One of the strengths of Lawrence Miller’s The Gorilla Guide® To… High Availability for Business-Critical Applications is the chapter on multi-cloud solutions, which can save you from a Netflix-style failure. But multi-cloud environments increase the pressure on the visibility of problems, security, and interoperability.

Miller starts with some common industry definitions. These include the five-tier model of availability for service-level agreements (SLAs) based on how many “nines” you guarantee (99% uptime, 99.9% uptime, etc.) and the concepts of recovery time objectives (RTOs) and recovery point objectives (RPOs). The value of these concepts is not so much in providing a guarantee to your users—because it’s hard to say for sure how a future disaster will proceed—but to get you thinking about what data and services your organization depends on and where vulnerabilities are.

Miller describes the features of robust architectures for high availability (See Figure 1), and illustrates the choices made by several corporations. He mentions the strengths and weaknesses of common services in today’s market and highlights the role of SIOS DataKeeper in protecting services.
