These are two of the seven capabilities that are in the platform perspective of the AWS Cloud Adoption Framework (AWS CAF). The platform perspective helps you build an enterprise-grade, scalable, hybrid cloud platform, modernize existing workloads, and implement new cloud-native solutions1. The other five capabilities are:

Platform architecture – Establish and maintain guidelines, principles, patterns, and guardrails for your cloud environment.

Platform engineering – Build a compliant multi-account cloud environment with enhanced security features, and packaged, reusable cloud products.

Platform operations – Manage and optimize your cloud environment with automation, monitoring, and incident response.

Application development – Develop and deploy cloud-native applications using modern architectures and best practices.

Application migration – Migrate your existing applications to the cloud using proven methodologies and tools.

Performance and capacity management, infrastructure protection, and change and release management are not capabilities of the platform perspective. They are part of the operations perspective, which helps you achieve operational excellence in the cloud2. The operations perspective comprises six capabilities:

Performance and capacity management – Monitor and optimize the performance and capacity of your cloud workloads.

Infrastructure protection – Protect your cloud infrastructure from unauthorized access, malicious attacks, and data breaches.

Change and release management – Manage changes and releases to your cloud workloads using automation and governance.

Configuration management – Manage the configuration of your cloud resources and applications using automation and version control.

Incident management – Respond to incidents affecting your cloud workloads using best practices and tools.

Service continuity management – Ensure the availability and resilience of your cloud workloads using backup, recovery, and disaster recovery strategies.

The cost of application software licenses is the company’s direct responsibility when it migrates its IT infrastructure from an on-premises data center to the AWS Cloud. Application software licenses are the agreements that grant users the right to use specific software products, such as operating systems, databases, or applications. Depending on the type and terms of the license, users may need to pay a fee to the software vendor or provider to use the software legally and access its features and updates. When users migrate their IT infrastructure to the AWS Cloud, they can choose to buy new licenses from AWS, bring their own licenses (BYOL), or use a combination of both. However, regardless of the option they choose, they are still responsible for complying with the license terms and paying the license fees to the software vendor or provider. AWS does not charge users for the application software licenses they bring or buy, but only for the AWS resources they use to run their applications. Therefore, thecost of application software licenses is the only cost among the options that is the company’s direct responsibility. The other costs are either included in the AWS service fees or covered by AWS.

According to the AWS shared responsibility model, AWS is responsible for security of the cloud, while customers are responsible for security in the cloud. This means that AWS is responsible for protecting the infrastructure that runs AWS services, such as hardware, software, networking, and facilities. Customers are responsible for managing their data, classifying their assets, and using IAM tools to apply the appropriate permissions. For abstracted services, such as Amazon DynamoDB, AWS operates the infrastructure layer, the operating system, and platforms, and provides customers with public endpoints to store and retrieve data. Customers are responsible for classifying their data, managing their encryption options, and configuring their access permissions. References: Shared Responsibility Model, Security and compliance in Amazon DynamoDB, [AWS Cloud Practitioner Essentials: Module 2 - Security in the Cloud]

Cost allocation tags are an AWS feature that allows for detailed tracking of cloud costs by tagging resources. These tags can be customized to represent departments, projects, or cost centers, enabling organizations to allocate and monitor expenses accurately. By using cost allocation tags, companies can create reports that break down costs by tag, providing granular insights into their cloud spending. This feature is critical for achieving detailed cost management and is a core part of AWS’s billing and cost management offerings.

AWS PrivateLink provides private connectivity between VPCs, AWS services, and on-premises applications without exposing traffic to the public internet. It enables private access to AWS services by creating private endpoints within a VPC, which enhances security and simplifies network architecture by keeping all communication on the AWS network. This service is ideal for scenarios where a company wants to connect AWS services and VPCs privately.

AWS Elastic Beanstalk is a service that enables you to quickly deploy and manage applications in the AWS Cloud without worrying about the infrastructure that runs those applications. You simply upload your application, and Elastic Beanstalk automatically handles the details of capacity provisioning, load balancing, scaling, and application health monitoring. Elastic Beanstalk supports several platform configurations for Java, .NET, PHP, Node.js, Python, Ruby, Go, and Docker web applications that can run on familiar servers such as Apache, Nginx, Passenger, and IIS. You can also use Elastic Beanstalk to launch a virtual machine (VM) and MySQL database on AWS with theleast operational effort. Amazon Elastic Container Service (Amazon ECS) is a fully managed container orchestration service that enables you to easily run, scale, and secure Docker containerized applications on AWS. However, it requires more operational effort than Elastic Beanstalk, as you need to define your application architecture and the specifications of the containers that run it. Amazon Lightsail is an easy-to-use cloud platform that offers everything you need to build an application or website, plus a cost-effective, monthly plan. It is designed for developers who have little or no prior cloud experience and want to launch and manage applications on AWS with minimal complexity. However, it does not support MySQL databases, and it requires more operational effort than Elastic Beanstalk, as you need to configure your VM and database settings. Amazon EC2 is a web service that provides secure, resizable compute capacity in the cloud. It allows you to launch a virtual machine (VM) and MySQL database on AWS, but it requires the most operational effort, as you need to provision, monitor, and manage your EC2 instances and database.

AWS Managed Services (AMS) is a service that operates AWS infrastructure on behalf of customers. It provides a secure and compliant environment, automates commonactivities, and applies best practices for provisioning, patching, backup, recovery, and monitoring5. AMS does not provide a framework for customers to operate their own workloads on AWS.

Agility in AWS Cloud computing means the ability to rapidly provision and deprovision AWS resources as needed, and the ability to experiment quickly with new ideas and solutions. Agility helps businesses to respond to changing customer demands, market opportunities, and competitive threats, and to innovate faster and cheaper. Agility also reduces the risk of failure, as businesses can test and validate their assumptions before committing to large-scale deployments. Some of the benefits of agility in AWS Cloud computing are:

The speed at which AWS resources are implemented: AWS provides a variety of services and tools that allow you to create, configure, and launch AWS resources in minutes, using the AWS Management Console, the AWS Command Line Interface (AWS CLI), the AWS Software Development Kits (AWS SDKs), or the AWS CloudFormation templates. You can also use the AWS Cloud Development Kit (AWS CDK) to define your AWS resources as code using familiar programming languages, and synthesize them into AWS CloudFormation templates. You can also use the AWS Service Catalog to create and manage standardized portfolios of AWS resources that meet your organizational policies and best practices. AWS also offers on-demand, pay-as-you-go pricing models, soyou only pay for the resources you use, and you can scale them up or down as your needs change12345

The ability to experiment quickly: AWS enables you to experiment quickly with new ideas and solutions, without having to invest in upfront capital or long-term commitments. You can use AWS to create and test multiple prototypes, hypotheses, and minimum viable products (MVPs) in parallel, and measure their performance and feedback. You can also use AWS to leverage existing services and solutions, such as AWS Marketplace, AWS Solutions, and AWS Quick Starts, that can help you accelerate your innovation process. AWS also supports a culture of experimentation and learning, by providing tools and resources for continuous integration and delivery (CI/CD), testing, monitoring, and analytics.

AWS Identity and Access Management (IAM) is a web service that helps you securely control access to AWS resources for your users. You use IAM to control who can use your AWS resources (authentication) and what resources they can use and in what ways (authorization). IAM is always available free of charge to users4.

AWS Application Composer is a service that allows users to visually design and build serverless applications. Users can drag and drop components, such as AWS Lambda functions, Amazon API Gateway endpoints, Amazon DynamoDB tables, and Amazon S3 buckets, to create aserverless application architecture. Users can also configure the properties, permissions, and dependencies of each component, and deploy the application to their AWS account with a few clicks. AWS Application Composer simplifies the design and configuration of serverless applications, and reduces the need to write code or use AWS CloudFormation templates. References: AWS Application Composer, AWS releases Application Composer to make serverless ‘easier’ but initial scope is limited

Amazon CloudWatch alarm is an AWS service or feature that can initiate an Amazon EC2 Auto Scaling action based on CPU utilization. Amazon CloudWatch is a monitoring and observability service that collects and tracks metrics, logs, events, and alarms for your AWS resources and applications. Amazon CloudWatch alarms are actions that you can configure to send notifications or automatically make changes to the resources you are monitoring based on rules that you define67.

Amazon EC2 Auto Scaling is a service that helps you maintain application availability and allows you to automatically add or remove EC2 instances according to definable conditions. You can create dynamic scaling policies that track a specific CloudWatch metric, such as CPU utilization, and define what action to take when the associated CloudWatch alarm is in ALARM. When the policy is in effect, Amazon EC2 Auto Scaling adjusts the group’s desired capacity up or down when the threshold of an alarm is breached89. References: 6: Cloud Monitoring - Amazon CloudWatch - AWS, 7: Amazon CloudWatch Documentation, 8: Dynamic scaling for Amazon EC2 Auto Scaling, 9: Amazon EC2 Auto Scaling Documentation

 The AWS service or feature that the company should use to categorize and track AWS usage cost based on business categories is cost allocation tags. Cost allocation tags are key-value pairs that users can attach to AWS resources to organize and track their AWS costs. Users can use cost allocation tags to filter and group their AWS costs by categories such as project, department, environment, or application. Users can also use cost allocation tags to generate detailed billing reports that show the costs associated with each tag3. AWS Organizations, AWS Security Hub, and AWS Cost and Usage Report are other AWS services or features that can help users with different aspects of their AWS usage, such as managing multiple accounts, monitoring security issues, or analyzing billing data, but they do not enable users to categorize and track AWS costs based on business categories.
