![]() The storage optimized families offer a wide range of storage sizes, either backed with HDDs or SSDs. This is in comparison to most instance families, such as compute optimized and general purpose types, which don’t have local storage but rely on attached EBS volumes instead. H, D, and I families are a good choice if your applications require high performance from its local storage. Since mid-2021 they’ve been made available with On-Demand pricing and are finding a wider set of use cases. Ranging from three to 24 TiB in available memory, these instances were originally made available for SAP HANA deployments with fixed-term commitments. ![]() Instances of the High Memory family offer the most memory of any EC2 instance and are primarily used for large in-memory databases. z1d is recommended for use cases like electronic design automation (EDA), gaming, or relational database workloads with high per-core licensing costs. The result is instances of both high-compute performance and high memory. Z1d instances deliver high single-thread performance with a sustained all core frequency of up to 4.0 GHz - the fastest of any cloud instance. They have a much higher proportion of memory than the R family. X1 and X2 instances are for enterprise-sized in-memory applications, like SAP HANA. The R families are ideal if you’re doing data mining, real-time processing of unstructured big data, or Hadoop/Spark clusters. These families have the lowest cost per GB of RAM, making them a good choice if your application is memory-bound. The X1, X2, R4, R5, R6, and z1d instances are for memory-intensive applications. X, R, z1d, and High Memory families: Memory optimized Examples of applications that are suited for the C family include front-end fleets for high-traffic websites, on-demand batch processing, distributed analytics, video encoding, and high-performance science and engineering applications. C family: Compute optimizedĬompute optimized instances are for applications that need a lot of compute power, with a higher ratio of vCPUs to memory and the lowest cost per vCPU. You might use a T instance for lower-throughput applications such as administrative applications, low-traffic websites, or development and testing. ![]() It’s best for applications that don’t require much performance most of the time but have periods where they’re active. You can think of this bursting as in-built elasticity. These instances are intended to operate at a low baseline performance for substantial blocks of time and can then automatically burst performance as needed. It’s also aimed at general-purpose workloads but is burstable. The T family is a lower-cost option than the M family. Then if you find that the instance is performance-limited by one of the hardware characteristics, you can switch over to another more specialized family. ![]() Unless you know you will be running a highly RAM/CPU/IO-intensive workload, you can usually start with an M instance and monitor its performance for a while. The M family has a good balance of CPU, RAM, and disk size/performance, making it the best choice for applications with consistent performance needs. The M and T families are the workhorses of EC2. Let’s run through a brief overview of the various EC2 instances families. You can infer it’s a fifth-generation type and its size is large. For example, c5.large means that the instance belongs to the C5 instance type (which is in the compute optimized family). Amazon EC2 family typesĮach EC2 instance family meets a target application profile in one of these categories:Īmazon describes an instance with the instance type first, then size. You are only charged for the instances while they are running, so when you’re done with your instances, you can spin them down and stop paying for them. You can do this manually from the AWS Management Console, or programmatically. This determines the resource capacity of the machine and hourly pricing. When you spin up an EC2 instance, you must choose the instance type (e.g., T3) and size (e.g., large). With EC2, you can easily provision an instance that’s secure, runs the software required for operating the business, and is available in minutes. At the heart of this service is the EC2 instance: virtual machines that run an operating system on top of resources like a CPU, memory, hard disk, etc. What is AWS EC2?ĪWS EC2 provides compute capacity in the cloud. This blog will review your options, summarize costs, and provide best practices for managing your EC2 usage. With hundreds of different instance types at various price points, it’s challenging to select the right compute resource for your needs and budget. Amazon Elastic Compute Cloud (EC2) is the most-used service on AWS.
