Amazon Web Services (AWS) Elastic Compute Cloud (EC2) promises
ease of deployment and instant scalability. However, EC2 also introduces
significant changes to coding, deployment and maintenance which makes this
infrastructure behave differently from traditional on-premise servers. These
differences lead to novel kinds of performance issues such as unpredictable EBS
disk I/O, EC2 instance ECU mismatches, and ELB load balancing traffic latency.
AWS offers a service for hosting applications on servers,
storage and other infrastructure with EC2. However, AWS only makes available a
small amount of information concerning the hardware that your applications are
running on. As a result it’s nearly impossible to know what is “running under
the hood” or which specific servers, storage drives and networking components are
processing your data and powering your applications. The nature of such a
service creates several distinct attributes that differ from running IT
hardware on-premise, and make certain issues more likely to occur.
Identifying the kinds of issues in AWS requires an
understanding of how EC2 works as well as visibility into an application and
underlying cloud-based infrastructure. Datadog’s new eBook explains how to gain
this visibility and details the five top EC2 performance issues to examine:
- Why these issues occur
- How to detect them
- How to resolve these issues, or avoid them all together
