Basically, an EC2 instance is a virtual server that replaces on-site, physical hardware. In a matter of minutes, you can spin up and configure an EC2 instance—or hundreds of them—with just a few clicks. The process is pretty simple: select an instance image called an AMIchoose an instance type based on desired performance, and then add any storage needed. They can be changed with ease. You just have to remember that when you terminate an EC2, your ephemeral storage the storage that is part of your EC2 is erased, but if you use an Elastic Block Storage EBS then you can reattach your storage volume to the new EC2 once launched.
You can also migrate certain instance types to other, better-suited performance families. With every configuration accounted for, there are overdifferent iterations of EC2. Amazon provides a list of 35 stock AMIs for you to choose from.
Within those greater families are unique instance types. Notice that T2, T3, M4, M5, and M5d are the different instance types, each having varying sizing options that range from nano to 24xlarge. From left to right, these instance types go from oldest to newest in generation. Over time, AWS deprecates the older generations.
All three of these components factor greatly when determining the overall price per hour Amazon charges you. Each pricing option is tailored to benefit a particular usage behavior. Properly evaluating your environment to determine the best payment method for each instance is crucial to avoiding wasteful spending. But be careful not to get too aggressive when trying to save—choosing the cheapest available option is not always the smartest choice. On-Demand is the standard pay-as-you-use payment option.
Essentially, these are a great first choice for anyone new to AWS who wants to learn without overcommitting. On-Demand Instances are also great for uncertain, flexible projects. How is that possible? And when the price goes above your set bidding threshold, your spot instances are interrupted via hibernation, stopping, or termination.
For the forward-thinker, Reserved Instances are a great resource. When using RIs, you also get the added optional benefit of reserving capacity in your preferred Availability Zones.
That sounds great, right? Well, the downside is that you have to commit to a long-term contract of at least one year. This means continuing to pay a monthly amount even if your need goes away in six months. Also, to get the most savings possible, you have to pay upfront.
Want to know more? Still like the idea of having your own physical server and have full control of your hardware? Dedicated Hosts are your solution. The difference is that Dedicated Instances may be provisioned on a different physical server each time preventing you from using your own software licenses tied to a specific socket, core, or CPU serial number.
This means that you would no longer pay for a full hour if you only use the instance in a running state for a few minutes. You also get the benefit of reserved instance pricing for multiple instances used within the hour. Remember that AWS EC2 pricing may still be expressed in the form of instance-hour on many of their pricing pages to preserve consistency. The more data that is sent out from AWS, the less expensive it gets.

I have an Amazon EC2 micro instance t1. I want to upgrade this instance to large. This is our production environment, so what is the best and risk-free way to do this? From my experience, the way I do it is create a snapshot of your current image, then once its done you'll see it as an option when launching new instances.
Simply launch it as a large instance at that point. This is my approach if I do not want any downtime i. If Downtime is acceptable then see Marcel Castilho's answer. Learn more.

When you launch an instance, the instance type that you specify determines the hardware of the host computer used for your instance.
Each instance type offers different compute, memory, and storage capabilities and are grouped in instance families based on these capabilities. Select an instance type based on the requirements of the application or software that you plan to run on your instance. Amazon EC2 provides each instance with a consistent and predictable amount of CPU capacity, regardless of its underlying hardware.
Amazon EC2 dedicates some resources of the host computer, such as CPU, memory, and instance storage, to a particular instance. Amazon EC2 shares other resources of the host computer, such as the network and the disk subsystem, among instances. If each instance on a host computer tries to use as much of one of these shared resources as possible, each receives an equal share of that resource.
However, when a resource is underused, an instance can consume a higher share of that resource while it's available.
Each instance type provides higher or lower minimum performance from a shared resource. For the best performance, we recommend that you use the current generation instance types when you launch new instances. To determine which instance types are available in which Regions or Availability Zones, use the describe-instance-type-offerings command. To describe the characteristics of an instance type, use the describe-instance-types command.
Amazon Web Services offers previous generation instances for users who have optimized their applications around these instances and have yet to upgrade. We encourage you to use the latest generation of instances to get the best performance, but we continue to support these previous generation instances.
If you are currently using a previous generation instance, you can see which current generation instance would be a suitable upgrade. For more information, see Previous Generation Instances. To determine which instance type best meets your needs, we recommend that you launch an instance and use your own benchmark application.
Because you pay by the instance secondit's convenient and inexpensive to test multiple instance types before making a decision. If your needs change, even after you make a decision, you can resize your instance later. For more information, see Changing the Instance Type. Amazon EC2 instances typically run on bit virtual Intel processors as specified in the instance type product pages.The M5s pack much more performance with an upgraded CPU 2. Making upgrading very attractive for teams willing to move to M5s, as you get M5 rates are slightly cheaper with much more performance over the M4s.
After Upgrading Instances from M4 to M5, you may face some issues like the box was not responding and they automatically get rebooted.

As your needs change, you might find that your instance is over-utilized the instance type is too small or under-utilized the instance type is too large.
If this is the case, you can change the size of your instance. For example, if your t2. You might also want to migrate from a previous generation instance type to a current generation instance type to take advantage of some features; for example, support for IPv6.
If the root device for your instance is an EBS volume, you can change the size of the instance simply by changing its instance type, which is known as resizing it. If the root device for your instance is an instance store volume, you must migrate your application to a new instance with the instance type that you need. For more information about root device volumes, see Storage for the Root Device.
When you resize an instance, you must select an instance type that is compatible with the configuration of the instance. If the instance type that you want is not compatible with the instance configuration you have, then you must migrate your application to a new instance with the instance type that you need.
When you resize an instance, the resized instance usually has the same number of instance store volumes that you specified when you launched the original instance.
With instance types that support NVMe instance store volumes which are available by defaultthe resized instance might have additional instance store volumes, depending on the AMI. Otherwise, you can migrate your application to an instance with a new instance type manually, specifying the number of instance store volumes that you need when you launch the new instance.
You can resize an instance only if its current instance type and the new instance type that you want are compatible in the following ways:. To check the virtualization type of your instance, see the Virtualization field on the details pane of the Instances screen in the Amazon EC2 console.
Architecture : AMIs are specific to the architecture of the processor, so you must select an instance type with the same processor architecture as the current instance type.
For example:. A1 instances are the only instances that support processors based on the Arm architecture. If you are resizing an instance type with a processor based on the Arm architecture, you are limited to the instance types that support a processor based on the Arm architecture.
The following instance types are the only instance types that support bit AMIs: t2. If you are resizing a bit instance, you are limited to these instance types. Network : Newer instance types must be launched in a VPC.Migrating Data to AWS: Understanding Your Options - AWS Online Tech Talks
Enhanced networking : Instance types that support enhanced networking require the necessary drivers installed.M5 instances offer a balance of compute, memory, and networking resources for a broad range of workloads. This includes web and application servers, small and mid-sized databases, cluster computing, gaming servers, caching fleets, and app development environments.
Additionally, M5d, M5dn, and M5ad instances have local storage, offering up to 3. Amazon EC2 M5n and M5dn instances are the latest addition to the M5 family and provide up to Gbps of networking throughput, optimized for network intensive applications. By leveraging the higher number of cores per processor, M5 instances provide customers with a higher instance density than the previous generation, which results in a reduction in per-instance TCO.
With the largest instance size of 24xlarge, customers can scale-up and consolidate their workloads on a fewer number of instances, to help lower their total cost of ownership. M5 instances are built on the AWS Nitro Systema combination of dedicated hardware and lightweight hypervisor which delivers practically all of the compute and memory resources of the host hardware to your instances for better overall performance and security.
M5n and M5dn instances leverage the fourth generation of custom Nitro card and Elastic Network Adapter ENA device to deliver up to Gbps of network throughput to a single instance.
These instances offer 4x the network bandwidth and packet process compared to the base M5 instances and are ideal for network intensive applications. These instances are a great fit for applications that need access to high-speed, low latency local storage including those that need temporary storage of data for scratch space, temporary files, and caches. M5 instances are built on the AWS Nitro System, a rich collection of building blocks that offloads many of the traditional virtualization functions to dedicated hardware.
By doing so, the AWS Nitro System enables high performance, high availability, and high security while also reducing virtualization overhead. With M5dn instances, local NVMe-based SSDs are physically connected to the host server and provide block-level storage that is coupled to the lifetime of the instance.
