AWS Certified Cloud Practitioner CLF-C02Demo

To become responsive to customer inquiries and feedback, organizations should realign teams around products and value streams (A) for customer focus, and adopt agile methodologies (C) to enable rapid iteration based on feedback. Creating new value propositions (B) addresses product strategy, new analytics platforms (D) focus on insights, and infrastructure migration (E) is a technical transition—none directly enable organizational responsiveness.

The AWS Support API, which lets a user open and manage support cases programmatically, is only available on the Business, Enterprise On-Ramp, and Enterprise Support plans; the Basic and Developer plans do not expose the Support API. Of the plans that include API access, Business Support is the lowest-cost tier, making it the most cost-effective choice for this requirement.

AWS serverless services shift management of the underlying infrastructure to AWS, including routine tasks such as capacity provisioning, scaling, and patching. Customers still retain responsibility for their application, security configuration, and operational observability.

Making frequent, small, reversible changes reduces the scope and impact of each change, supports faster troubleshooting and remediation, and allows changes to be rolled back. AWS identifies this as an Operational Excellence design principle.

AWS Snowmobile provides offline, physical transport for very large data migrations, supporting tens of petabytes to exabytes. It is designed for moving data from an on-premises data center to AWS without transferring it over an internet connection.

AWS Transit Gateway acts as a central hub or 'cloud router' that simplifies connections between multiple VPCs and on-premises networks, eliminating complex point-to-point peering relationships. Direct Connect provides connectivity but not routing, Amazon Connect is a contact center service, and Route 53 is DNS.

The AWS CAF Platform perspective includes capabilities for designing and implementing well-architected technology infrastructure, including data and analytics architecture. This perspective focuses on technical excellence across compute, storage, database, and analytics services. Security, Governance, and Operations perspectives handle different domains—security policies, business controls, and operational management respectively.

AWS Fargate is AWS's serverless container compute engine, designed specifically to run Docker containers without requiring you to manage EC2 instances, clusters, or infrastructure scaling. SQS is a messaging service, Elastic Beanstalk is a platform-as-a-service, and SageMaker is for machine learning—none provide serverless container compute.

AWS CloudTrail records actions performed by users, roles, and AWS services, including Amazon EC2 API calls and management-console actions. Its event history can be searched to determine the request made against an EC2 instance, who made it, and when it occurred.

Amazon Neptune is AWS’s fully managed graph database service for applications that work with highly connected data. It supports graph query languages including Gremlin, openCypher, and SPARQL. AWS Neptune documentation

AWS Direct Connect provides a dedicated private network connection between an on-premises data center, office, or colocation environment and AWS. A private virtual interface can provide access to workloads in an Amazon VPC using private IP addresses.

AWS Application Discovery Service collects detailed information about on-premises infrastructure, including server configurations, resource utilization, and dependencies, to aid in migration planning. Application Migration Service actually performs the migration, not the discovery phase. This service is perfect for understanding existing usage before replicating workloads.

AWS manages and controls the underlying cloud infrastructure, including the host operating system and virtualization layer. Updating the Nitro Hypervisor is therefore an AWS responsibility. Customers remain responsible for security in the cloud, including their EC2 guest operating systems, IAM policies, and data-encryption configuration choices.

Savings Plans reduce Amazon EC2 costs in exchange for a commitment to consistent compute usage over a one- or three-year term. They are suited to steady-state, predictable workloads that require uninterrupted availability, whereas Spot Instances can be interrupted.

AWS IAM Access Analyzer identifies resources shared with external principals by analyzing resource-based policies and generating findings. Its external-access analysis supports both Amazon S3 buckets and IAM roles.

The AWS CAF Envision phase focuses on demonstrating how cloud can accelerate business outcomes by identifying and prioritizing transformation opportunities that align with strategic business objectives.

AWS Software Development Kits (SDKs) provide the programming-language libraries and APIs that let application code call AWS services programmatically.

The AWS CAF Security perspective includes Incident response, which establishes mechanisms to respond to and mitigate security incidents, and Infrastructure protection, which protects systems and services from unintended or unauthorized access and vulnerabilities.

Replatform (also called 'lift, tinker, and shift') involves migrating self-managed MySQL to AWS RDS for MySQL with some level of optimization to leverage cloud capabilities. Rehost (lift and shift) would be used for minimal-change migrations, but managed database services typically require configuration adjustments, making replatforming the appropriate strategy.

Amazon SQS FIFO queues provide durable messaging between application components and preserve the order in which messages are sent and received within each message group. FIFO queues also support exactly-once processing.

AWS Countdown supports product-launch and go-live events by assessing operational readiness, identifying and mitigating risks, and planning capacity. It is included with AWS Enterprise Support at no additional charge.

The AWS Pricing Calculator projects estimated monthly costs for AWS services based on configuration selections. It does not calculate historical costs from bills, explain pricing strategies in detail, or provide access to actual billing—those are provided by the AWS Cost Explorer, documentation, and the AWS Billing Console respectively.

Migrating to AWS lets a company reach customers across a global network of Regions and Availability Zones and provision new infrastructure in minutes rather than months, giving it increased global reach and agility and the ability to deploy globally in minutes. Security auditing and IT staffing responsibilities shift under the shared responsibility model rather than disappearing, and redundancy is not automatic for every compute service unless it is explicitly architected for high availability.

Amazon QuickSight is AWS's business intelligence service that creates interactive dashboards and visualizations from business data. Macie is for data security and privacy discovery, Aurora is a relational database, and CloudTrail logs API activity, none of which provide BI dashboards.
