Why my EC2 instance is very slow?

There are many possible causes of this problem, including problems with an external service that your instance relies on, disk thrashing, or network connectivity issues. This article discusses one common cause: depleted I/O burst credits on the gp2 root volume.

Do EC2 instances fail?

EC2 instances can fail fairly frequently. Sometimes this happens because you are running on ancient hardware, sometimes because AWS has to do some emergency patches on the underlying hardware or software. The right way to build something is to expect things to fail frequently and without warning.

What is a micro instance?

Micro instances are optimized for applications that require lower throughput, but which still may consume significant compute cycles periodically. Micro instances provide a small amount of consistent CPU resources, and also allow you to burst CPU capacity when additional cycles are available.

Which issues will cause an EC2 instance status check to fail?

An instance status check failure can be caused due to any of the following problems with the instance:

  • Networking or startup configuration issues.
  • Exhausted memory.
  • File system issues.
  • Failure to boot the operating system.
  • Failure to mount volumes correctly.
  • Incompatible drivers.

What are the different types of EC2 instances?

Amazon EC2 Instance Types. Amazon EC2 provides a wide selection of instance types optimized to fit different use cases. Instance types comprise varying combinations of CPU, memory, storage, and networking capacity and give you the flexibility to choose the appropriate mix of resources for your applications.

What is a burstable performance instance in Amazon EC2?

Amazon EC2 allows you to choose between Fixed Performance Instances (e.g. M5, C5, and R5) and Burstable Performance Instances (e.g. T3). Burstable Performance Instances provide a baseline level of CPU performance with the ability to burst above the baseline.

Does selectselect EC2 support cluster networking?

Select EC2 instances support cluster networking when launched into a common cluster placement group. A cluster placement group provides low-latency networking between all instances in the cluster. The bandwidth an EC2 instance can utilize depends on the instance type and its networking performance specification.

What is the difference between Amazon EC2 and Amazon EBS?

Amazon EC2 allows you to choose between multiple storage options based on your requirements. Amazon EBS is a durable, block-level storage volume that you can attach to a single, running Amazon EC2 instance. You can use Amazon EBS as a primary storage device for data that requires frequent and granular updates.
