Amazon EC2 pricing

 


Amazon Elastic Compute Cloud (EC2) is a cloud computing service provided by Amazon Web Services (AWS) that allows you to rent virtual servers, known as instances. EC2 pricing can be somewhat complex due to various cost factors. Here are some key points to understand:

  1. Instance Types: EC2 offers a variety of instance types optimized for different use cases, such as general-purpose, compute-optimized, memory-optimized, and more. The pricing varies based on the instance type you choose.

  2. Pricing Models:

    • On-Demand Instances: You pay for computing capacity by the hour or second without any upfront fees or long-term commitments. Sample use cases for On-Demand Instances include developing testing and running applications with unpredictable usage patterns. On-demand instances are not recommended for workloads that last a year or longer because these workloads can experience greater cost savings using Reserved Instances.

    • Reserved Instances (RIs): RIs offer significant discounts compared to On-Demand instances but require a one- or three-year commitment. They are ideal for predictable workloads. Reserved Instances are a billing discount for using On-Demand Instances in your account. There are two available types of Reserved Instances:

      • Standard Reserved Instances

      • Convertible Reserved Instances

      You can purchase Standard Reserved and Convertible Reserved Instances for a 1-year or 3-year term. You realize greater cost savings with the 3-year option. 

    • Spot Instances: These instances allow you to use spare AWS capacity at a much lower price but can be terminated if the capacity is needed elsewhere. Spot Instances are ideal for workloads with flexible start and end times or can withstand interruptions. Spot Instances uses unused Amazon EC2 computing capacity and offers cost savings at up to 90% off of On-Demand prices.
      Suppose you have a background processing job that can start and stop as needed (such as the data processing job for a customer survey). You want to start and stop the processing job without affecting the overall operations of your business. If you make a Spot request and Amazon EC2 capacity is available, your Spot Instance launches. However, if you make a Spot request and Amazon EC2 capacity is unavailable, the request is unsuccessful until capacity becomes available. The unavailable capacity might delay the launch of your background processing job.
      After you have launched a Spot Instance, if capacity is no longer available or demand for Spot Instances increases, your instance may be interrupted. This might not pose any issues for your background processing job. However, in the earlier example of developing and testing applications, you would likely want to avoid unexpected interruptions. Therefore, choose a different EC2 instance type ideal for those tasks.

    • Dedicated Hosts: These provide physical servers dedicated to your use and have their own pricing model. You can use your existing per-socket, per-core, or per-VM software licenses to help maintain license compliance. You can purchase On-Demand Dedicated Hosts and Dedicated Hosts Reservations. Of all the Amazon EC2 options that were covered, Dedicated Hosts are the most expensive.

  3. Regions and Availability Zones: EC2 pricing can also vary by the AWS region and the specific Availability Zone within that region where your instances are hosted.

  4. Operating Systems: Different operating systems (e.g., Linux and Windows) may have different pricing.

  5. Data Transfer: Data transfer in and out of EC2 instances may incur additional charges, depending on the amount of data transferred.

  6. Storage: You'll be charged for additional storage volumes attached to your EC2 instances.

  7. Additional Services: Their costs will be added to your bill if you use additional AWS services with EC2 instances, such as load balancers or EBS (Elastic Block Store) volumes.

  8. Elastic IP Addresses: There may be charges associated with Elastic IP addresses if they are not attached to a running instance.

To get precise pricing information for your specific use case, it's recommended to visit the official AWS Pricing page or use the AWS Pricing Calculator, which allows you to estimate the cost of running EC2 instances with various configurations.

Remember that AWS pricing can change over time, so it's essential to regularly check the AWS website for the most up-to-date pricing information and monitor your AWS billing dashboard to understand your specific costs.

Cloud computing

  Cloud computing is a technology model that enables access to a shared pool of computing resources and services over the Internet. Instead of owning and maintaining physical servers and data centers, organizations can use cloud computing services provided by cloud service providers. These services include computing power, storage, databases, networking, software, and more. Cloud computing services can be categorized into several main models: Infrastructure as a Service (IaaS): IaaS provides virtualized computing resources over the Internet. Users can rent virtual machines, storage, and networking components, allowing them to run and manage their operating systems and applications. Platform as a Service (PaaS): PaaS offers a platform that includes the underlying infrastructure, development tools, and services to build, deploy, and manage applications. Users focus on coding and application development while the platform handles the underlying infrastructure. Software as a Service ...

AWS Free Tier

The AWS Free Tier is designed to give you hands-on experience with a range of Amazon Web Services (AWS) products and services without charging you for usage up to a specific limit. This tier primarily benefits new AWS customers, allowing them to try different AWS services and gain practical experience before committing to more extensive usage. The Free Tier includes offers that are available for 12 months following your AWS sign-up date, as well as offers that are always free. Here are the main components of the AWS Free Tier: 12-Months Free: These offers are available to new AWS customers and are valid for 12 months following your AWS sign-up date. After the 12-month free usage term, you pay standard, pay-as-you-go service rates. Always Free: These offers do not expire and are available to all AWS customers. They provide limited access to a range of AWS services for free forever. However, the usage limits reset monthly. Trials: Short-term trial offers start when you activate a part...
