<a name="cost-05"></a>

Amazon EC2, Amazon EBS, and Amazon S3 are building-block AWS services. Managed services, such as Amazon RDS and Amazon DynamoDB, are higher level, or application level, AWS services. By selecting the appropriate building blocks and managed services, you can optimize this workload for cost. For example, using managed services, you can reduce or remove much of your administrative and operational overhead, freeing you to work on applications and business-related activities.

# COST05-BP01 Identify organization requirements for cost
<a name="cost_select_service_requirements"></a>

 Work with team members to define the balance between cost optimization and other pillars, such as performance and reliability, for this workload. 

 **Level of risk exposed if this best practice is not established:** High 

## Implementation guidance
<a name="implementation-guidance"></a>

 In most organizations, the information technology (IT) department is comprised of multiple small teams, each with its own agenda and focus area, that reflects the specialisies and skills of its team members. You need to understand your organization’s overall objectives, priorities, goals and how each department or project contributes to these objectives. Categorizing all essential resources, including personnel, equipment, technology, materials, and external services, is crucial for achieving organizational objectives and comprehensive budget planning. Adopting this systematic approach to cost identification and understanding is fundamental for establishing a realistic and robust cost plan for the organization. 

 When selecting services for your workload, it is key that you understand your organization priorities. Create a balance between cost optimization and other AWS Well-Architected Framework pillars, such as performance and reliability. This process should be conducted systematically and regularly to reflect changes in the organization's objectives, market conditions, and operational dynamics. A fully cost-optimized workload is the solution that is most aligned to your organization’s requirements, not necessarily the lowest cost. Meet with all teams in your organization, such as product, business, technical, and finance to collect information. Evaluate the impact of tradeoffs between competing interests or alternative approaches to help make informed decisions when determining where to focus efforts or choosing a course of action. 

 For example, accelerating speed to market for new features may be emphasized over cost optimization, or you may choose a relational database for non-relational data to simplify the effort to migrate a system, rather than migrating to a database optimized for your data type and updating your application. 

### Implementation steps
<a name="implementation-steps"></a>
+ ** Identify organization requirements for cost:** Meet with team members from your organization, including those in product management, application owners, development and operational teams, management, and financial roles. Prioritize the Well-Architected pillars for this workload and its components. The output should be a list of the pillars in order. You can also add a weight to each pillar to indicate how much additional focus it has, or how similar the focus is between two pillars.
+  **Address the technical debt and document it:** During the workload review, address the technical debt. Document a backlog item to revisit the workload in the future, with the goal of refactoring or re-architecting to optimize it further. It's essential to clearly communicate the trade-offs that were made to other stakeholders.

# COST05-BP02 Analyze all components of the workload
<a name="cost_select_service_analyze_all"></a>

 Verify every workload component is analyzed, regardless of current size or current costs. The review effort should reflect the potential benefit, such as current and projected costs. 

 **Level of risk exposed if this best practice is not established:** High 

## Implementation guidance
<a name="implementation-guidance"></a>

 Workload components, which are designed to deliver business value to the organization, may encompass various services. For each component, one might choose specific AWS Cloud services to address business needs. This selection could be influenced by factors such as familiarity with or prior experience using these services. 

 After identifying your organization's requirements as mentioned in [COST05-BP01 Identify organization requirements for cost](https://docs.aws.amazon.com/wellarchitected/latest/cost-optimization-pillar/cost_select_service_requirements.html), perform a thorough analysis on all components in your workload. Analyze each component considering current and projected costs and sizes. Consider the cost of analysis against any potential workload savings over its lifecycle. The effort expended on the analysis of all components of this workload should correspond to the potential savings or improvements anticipated from optimization of that specific component. For example, if the cost of the proposed resource is \$110 per month, and under forecasted loads would not exceed \$115 per month, spending a day of effort to reduce costs by 50% (five dollars per month) could exceed the potential benefit over the life of the system. Use a faster and more efficient data-based estimation to create the best overall outcome for this component. 

 Workloads can change over time, and the right set of services may not be optimal if the workload architecture or usage changes. Analysis for selection of services must incorporate current and future workload states and usage levels. Implementing a service for future workload state or usage may reduce overall costs by reducing or removing the effort required to make future changes. For example, using EMR Serverless might be the appropriate choice initially. However, as consumption for that service increases, transitioning to EMR on EC2 could reduce costs for that component of the workload. 

 [AWS Cost Explorer](https://aws.amazon.com/aws-cost-management/aws-cost-explorer/) and the AWS Cost and Usage Reports ([CUR](https://aws.amazon.com/aws-cost-management/aws-cost-and-usage-reporting/)) can analyze the cost of a proof of concept (PoC) or running environment. You can also use [AWS Pricing Calculator](https://calculator.aws/#/) to estimate workload costs. 

 Write a workflow to be followed by technical teams to review their workloads. Keep this workflow simple, but also cover all the necessary steps to make sure the teams understand each component of the workload and its pricing. Your organization can then follow and customize this workflow based on the specific needs of each team. 

1.  **List each service in use for your workload:** This is a good starting point. Identify all of the services currently in use and where costs are originate from. 

1.  **Understand how pricing works for those services:** Understand the [pricing model](https://aws.amazon.com/pricing/) of each service. Different AWS services have different pricing models based on factors like usage volume, data transfer, and feature-specific pricing. 

1.  **Focus on the services that have unexpected workload costs and that do not align with your expected usage and business outcome:** Identify outliers or services where the cost is not proportional to the value or usage by using AWS Cost Explorer or AWS Cost and Usage Reports. It's important to correlate costs with business outcomes to prioritize optimization efforts. 

1.  **AWS Cost Explorer, CloudWatch Logs, VPC Flow Logs, and Amazon S3 Storage Lens to understand the root cause of those high costs:** These tools are instrumental in the diagnosis of high costs. Each service offers a different lens to view and analyze usage and costs. For instance, Cost Explorer helps determine overall cost trends, CloudWatch Logs provides operational insights, VPC Flow Logs displays IP traffic, and Amazon S3 Storage Lens is useful for storage analytics. 

1.  **Use AWS Budgets to set budgets for certain amounts for services or accounts:** Setting budgets is a proactive way to manage costs. Use AWS Budgets to set custom budget thresholds and receive alerts when costs exceed those thresholds. 

1.  **Configure Amazon CloudWatch alarms to send billing and usage alerts:** Set up monitoring and alerts for cost and usage metrics. CloudWatch alarms can notify you when certain thresholds are breached, which improves intervention response time. 

 Facilitate notable enhancement and financial savings over time through strategic review of all workload components and irrespective of their present attributes. The effort invested in this review process should be deliberate, with careful consideration of the potential advantages that might be realized. 

### Implementation steps
<a name="implementation-steps"></a>
+  **List the workload components:** Build a list of your workload's components. Use this list to verify that each component was analyzed. The effort spent should reflect the criticality to the workload as defined by your organization's priorities. Group together resources functionally to improve efficiency (for example, production database storage, if there are multiple databases). 
+  **Prioritize the component list:** Take the component list and prioritize it in order of effort. This is typically in order of the cost of the component, from most expensive to least expensive or the criticality as defined by your organization's priorities. 
+  **Perform the analysis:** For each component on the list, review the options and services available, and choose the option that aligns best with your organizational priorities.

# COST05-BP03 Perform a thorough analysis of each component
<a name="cost_select_service_thorough_analysis"></a>

 Look at overall cost to the organization of each component. Calculate the total cost of ownership by factoring in cost of operations and management, especially when using managed services by cloud provider. The review effort should reflect potential benefit (for example, time spent analyzing is proportional to component cost). 

 **Level of risk exposed if this best practice is not established:** High 

## Implementation guidance
<a name="implementation-guidance"></a>

 Consider the time savings that will allow your team to focus on retiring technical debt, innovation, value-adding features and building what differentiates the business. For example, you might need to lift and shift (also known as rehost) your databases from your on-premises environment to the cloud as rapidly as possible and optimize later. It is worth exploring the possible savings attained by using managed services on AWS that may remove or reduce license costs. Managed services on AWS remove the operational and administrative burden of maintaining a service, such as patching or upgrading the OS, and allow you to focus on innovation and business. 

 Since managed services operate at cloud scale, they can offer a lower cost per transaction or service. You can make potential optimizations in order to achieve some tangible benefit, without changing the core architecture of the application. For example, you may be looking to reduce the amount of time you spend managing database instances by migrating to a database-as-a-service platform like [Amazon Relational Database Service (Amazon RDS)](https://aws.amazon.com/rds/) or migrating your application to a fully managed platform like [AWS Elastic Beanstalk](https://aws.amazon.com/elasticbeanstalk/). 

Usually, managed services have attributes that you can set to ensure sufficient capacity. You must set and monitor these attributes so that your excess capacity is kept to a minimum and performance is maximized. You can modify the attributes of AWS Managed Services using the AWS Management Console or AWS APIs and SDKs to align resource needs with changing demand. For example, you can increase or decrease the number of nodes on an Amazon EMR cluster (or an Amazon Redshift cluster) to scale out or in.

You can also pack multiple instances on an AWS resource to activate higher density usage. For example, you can provision multiple small databases on a single Amazon Relational Database Service (Amazon RDS) database instance. As usage grows, you can migrate one of the databases to a dedicated Amazon RDS database instance using a snapshot and restore process.

When provisioning workloads on managed services, you must understand the requirements of adjusting the service capacity. These requirements are typically time, effort, and any impact to normal workload operation. The provisioned resource must allow time for any changes to occur, provision the required overhead to allow this. The ongoing effort required to modify services can be reduced to virtually zero by using APIs and SDKs that are integrated with system and monitoring tools, such as Amazon CloudWatch.

[Amazon RDS](https://aws.amazon.com/rds/), [Amazon Redshift](https://aws.amazon.com/redshift/), and [Amazon ElastiCache](https://aws.amazon.com/elasticache/) provide a managed database service. [Amazon Athena](https://aws.amazon.com/athena/), [Amazon EMR](https://aws.amazon.com/emr/), and [Amazon OpenSearch Service](https://aws.amazon.com/opensearch-service/) provide a managed analytics service.

[AMS](https://aws.amazon.com/managed-services/) is a service that operates AWS infrastructure on behalf of enterprise customers and partners. It provides a secure and compliant environment that you can deploy your workloads onto. AMS uses enterprise cloud operating models with automation to allow you to meet your organization requirements, move into the cloud faster, and reduce your on-going management costs.

**Implementation steps**
+ ** Perform a thorough analysis: **Using the component list, work through each component from the highest priority to the lowest priority. For the higher priority and more costly components, perform additional analysis and assess all available options and their long term impact. For lower priority components, assess if changes in usage would change the priority of the component, and then perform an analysis of appropriate effort. 
+  **Compare managed and unmanaged resources:** Consider the operational cost for the resources you manage and compare them with AWS managed resources. For example, review your databases running on Amazon EC2 instances and compare with Amazon RDS options (an AWS managed service) or Amazon EMR compared to running Apache Spark on Amazon EC2. When moving from a self-managed workload to a AWS fully managed workload, research your options carefully. The three most important factors to consider are the [type of managed service](https://aws.amazon.com/products/?&aws-products-all.q=managed) you want to use, the process you will use to [migrate your data](https://aws.amazon.com/big-data/datalakes-and-analytics/migrations/) and understand the [AWS shared responsibility model](https://aws.amazon.com/compliance/shared-responsibility-model/).

# COST05-BP04 Select software with cost-effective licensing
<a name="cost_select_service_licensing"></a>

 Open-source software eliminates software licensing costs, which can contribute significant costs to workloads. Where licensed software is required, avoid licenses bound to arbitrary attributes such as CPUs, look for licenses that are bound to output or outcomes. The cost of these licenses scales more closely to the benefit they provide. 

 **Level of risk exposed if this best practice is not established:** Low 

## Implementation guidance
<a name="implementation-guidance"></a>

 Open source originated in the context of software development to indicate that the software complies with certain free distribution criteria. Open source software is composed of source code that anyone can inspect, modify, and enhance. Based on business requirements, skill of engineers, forecasted usage, or other technology dependencies, organizations can consider using open source software on AWS to minimize their license costs. In other words, the cost of software licenses can be reduced through the use of [open source software](https://aws.amazon.com/what-is/open-source/). This can have significant impact on workload costs as the size of the workload scales. 

 Measure the benefits of licensed software against the total cost to optimize your workload. Model any changes in licensing and how they would impact your workload costs. If a vendor changes the cost of your database license, investigate how that impacts the overall efficiency of your workload. Consider historical pricing announcements from your vendors for trends of licensing changes across their products. Licensing costs may also scale independently of throughput or usage, such as licenses that scale by hardware (CPU bound licenses). These licenses should be avoided because costs can rapidly increase without corresponding outcomes. 

 For instance, operating an Amazon EC2 instance in us-east-1 with a Linux operating system allows you to cut costs by approximately 45%, compared to running another Amazon EC2 instance that runs on Windows. 

 The [AWS Pricing Calculator](https://calculator.aws/) offers a comprehensive way to compare the costs of various resources with different license options, such as Amazon RDS instances and different database engines. Additionally, the AWS Cost Explorer provides an invaluable perspective for the costs of existing workloads, especially those that come with different licenses. For license management, [AWS License Manager](https://aws.amazon.com/license-manager) offers a streamlined method to oversee and handle software licenses. Customers can deploy and operationalize their preferred open source software in the AWS Cloud. 

### Implementation steps
<a name="implementation-steps"></a>
+ ** Analyze license options:** Review the licensing terms of available software. Look for open source versions that have the required functionality, and whether the benefits of licensed software outweigh the cost. Favorable terms align the cost of the software to the benefits it provides.
+ ** Analyze the software provider:** Review any historical pricing or licensing changes from the vendor. Look for any changes that do not align to outcomes, such as punitive terms for running on specific vendors hardware or platforms. Additionally, look for how they perform audits, and penalties that could be imposed.

# COST05-BP05 Select components of this workload to optimize cost in line with organization priorities
<a name="cost_select_service_select_for_cost"></a>

 Factor in cost when selecting all components for your workload. This includes using application-level and managed services or serverless, containers, or event-driven architecture to reduce overall cost. Minimize license costs by using open-source software, software that does not have license fees, or alternatives to reduce spending. 

 **Level of risk exposed if this best practice is not established:** Medium 

## Implementation guidance
<a name="implementation-guidance"></a>

 Consider the cost of services and options when selecting all components. This includes using application level and managed services, such as [Amazon Relational Database Service](https://aws.amazon.com/rds/) (Amazon RDS), [Amazon DynamoDB](https://aws.amazon.com/dynamodb/), [Amazon Simple Notification Service](https://aws.amazon.com/sns/) (Amazon SNS), and [Amazon Simple Email Service](https://aws.amazon.com/ses/) (Amazon SES) to reduce overall organization cost. 

 Use serverless and containers for compute, such as [AWS Lambda](https://aws.amazon.com/lambda/) and [Amazon Simple Storage Service](https://aws.amazon.com/s3/) (Amazon S3) for static websites. Containerize your application if possible and use AWS Managed Container Services such as [Amazon Elastic Container Service](https://aws.amazon.com/ecs/) (Amazon ECS) or [Amazon Elastic Kubernetes Service](https://aws.amazon.com/eks/) (Amazon EKS). 

 Minimize license costs by using open-source software, or software that does not have license fees (for example, Amazon Linux for compute workloads or migrate databases to Amazon Aurora). 

 You can use serverless or application-level services such as [Lambda](https://aws.amazon.com/lambda/), [Amazon Simple Queue Service (Amazon SQS)](https://aws.amazon.com/sqs/), [Amazon SNS](https://aws.amazon.com/sqs/), and [Amazon SES](https://aws.amazon.com/ses/). These services remove the need for you to manage a resource and provide the function of code execution, queuing services, and message delivery. The other benefit is that they scale in performance and cost in line with usage, allowing efficient cost allocation and attribution. 

 Using [event-driven architecture](https://aws.amazon.com/what-is/eda/) is also possible with serverless services. Event-driven architectures are push-based, so everything happens on demand as the event presents itself in the router. This way, you’re not paying for continuous polling to check for an event. This means less network bandwidth consumption, less CPU utilization, less idle fleet capacity, and fewer SSL/TLS handshakes. 

 For more information on serverless, see [Well-Architected Serverless Application lens whitepaper.](https://docs.aws.amazon.com/wellarchitected/latest/serverless-applications-lens/welcome.html) 

### Implementation steps
<a name="implementation-steps"></a>
+  **Select each service to optimize cost:** Using your prioritized list and analysis, select each option that provides the best match with your organizational priorities. Instead of increasing the capacity to meet the demand, consider other options which may give you better performance with lower cost. For example, if you need to review expected traffic for your databases on AWS, consider either increasing the instance size or using Amazon ElastiCache services (Redis or Memcached) to provide cached mechanisms for your databases. 
+  **Evaluate event-driven architecture:** Using serverless architecture also allows you to build event-driven architecture for distributed microservice-based applications, which helps you build scalable, resilient, agile and cost-effective solutions.

# COST05-BP06 Perform cost analysis for different usage over time
<a name="cost_select_service_analyze_over_time"></a>

 Workloads can change over time. Some services or features are more cost effective at different usage levels. By performing the analysis on each component over time and at projected usage, the workload remains cost-effective over its lifetime. 

 **Level of risk exposed if this best practice is not established:** Medium 

## Implementation guidance
<a name="implementation-guidance"></a>

As AWS releases new services and features, the optimal services for your workload may change. Effort required should reflect potential benefits. Workload review frequency depends on your organization requirements. If it is a workload of significant cost, implementing new services sooner will maximize cost savings, so more frequent review can be advantageous. Another initiation for review is change in usage patterns. Significant changes in usage can indicate that alternate services would be more optimal.

 If you need to move data into AWS Cloud, you can select any wide variety of services AWS offers and partner tools to help you migrate your data sets, whether they are files, databases, machine images, block volumes, or even tape backups. For example, to move a large amount of data to and from AWS or process data at the edge, you can use one of the AWS purpose-built devices to cost effectively move petabytes of data offline. Another example is for higher data transfer rates, a direct connect service may be cheaper than a VPN which provides the required consistent connectivity for your business. 

 Based on the cost analysis for different usage over time, review your scaling activity. Analyze the result to see if the scaling policy can be tuned to add instances with multiple instance types and purchase options. Review your settings to see if the minimum can be reduced to serve user requests but with a smaller fleet size, and add more resources to meet the expected high demand. 

 Perform cost analysis for different usage over time by discussing with stakeholders in your organization and use [AWS Cost Explorer’s](https://docs.aws.amazon.com/cost-management/latest/userguide/ce-forecast.html) forecast feature to predict the potential impact of service changes. Monitor usage level launches using AWS Budgets, CloudWatch billing alarms and AWS Cost Anomaly Detection to identify and implement the most cost-effective services sooner. 

**Implementation steps**
+ ** Define predicted usage patterns: **Working with your organization, such as marketing and product owners, document what the expected and predicted usage patterns will be for the workload. Discuss with business stakeholders about both historical and forecasted cost and usage increases and make sure increases align with business requirements. Identify calendar days, weeks, or months where you expect more users to use your AWS resources, which indicate that you should increase the capacity of the existing resources or adopt additional services to reduce the cost and increase performance. 
+ ** Perform cost analysis at predicted usage:** Using the usage patterns defined, perform analysis at each of these points. The analysis effort should reflect the potential outcome. For example, if the change in usage is large, a thorough analysis should be performed to verify any costs and changes. In other words, when cost increases, usage should increase for business as well.
