AWS Certified Developer Associate - EXAM REVIEW - 2021

Explore cloud fundamentals, including elasticity, pay-as-you-go operational expenditure, and global deployment across AWS regions and availability zones to achieve high availability and low latency.

Explore AWS compute services like EC2 with ELB, Elastic Beanstalk, ECS with Fargate, and Lambda, highlighting serverless options and when you manage EC2 clusters.

Explore AWS Lambda and API Gateway serverless architecture, focusing on execution context, concurrency, provisioned and reserved concurrency, invocation types, versions, aliases, and layers for scalable, managed code.

Explore API Gateway as the front door to AWS Lambda, covering REST API, HTTP API, and WebSocket types, with caching, throttling, canary releases, and monitoring through CloudWatch and X-Ray.

Explore identity federation and Amazon Cognito, including user pools and identity pools, OpenID Connect and SAML integration, social sign-in, multi-factor authentication, and API Gateway authorizers and token-based access.

Explore Amazon S3 as flexible object storage with buckets and keys, prefix-based search, storage classes, versioning, lifecycle rules, replication, and static website hosting for optimized cost, durability, and access.

Explore S3 security and access controls, including bucket policies, ACL, pre-signed URLs, access points, versioning, object lock, and lifecycle, and compare Glacier for archives.

Explore block, file, and hybrid storage in AWS, detailing EBS, instance store, S3, EFS, FSx, and storage gateway options for on-premise to cloud integration.

Explore authentication and authorization in AWS IAM, covering users, groups, roles, policies, identity-based and resource-based policies, cross-account access, instance profiles, MFA, and best practices for least privilege.

Explore data encryption with AWS KMS and CloudHSM, including envelope encryption, symmetric and asymmetric keys, master keys, and how S3 and other services encrypt data using CMKs and data keys.

Discover AWS databases overview: relational RDS with OLTP, analytics Redshift for OLAP, document and key stores with DynamoDB, graph data with Neptune, and in-memory caches with ElastiCache.

Explore Amazon RDS for OLTP workloads, including multi-az high availability, read replicas for scalability, automated backups, and point-in-time restores, plus Amazon Aurora's high-performance, multi-az storage and global database options.

DynamoDB offers a fast, scalable NoSQL key-value and document database with schemaless tables, auto partitioning, and options for provisioned or on-demand capacity, including primary keys, secondary indexes, and transactional operations.

Explore DynamoDB API errors, batch getitem and batch write item results, and design partition keys with time to live attributes and streams for scalable, efficient access.

Design VPCs and subnets with public and private zones, internet gateway, and NAT options; compare NACLs and security groups, and review VPC peering, endpoints, flow logs, and on-prem connections.

Decouple applications using asynchronous communication with SQS and SNS. Compare synchronous and asynchronous patterns, and learn SQS features like visibility timeout, delay, retention, deduplication, and dead-letter queues, plus SNS pub-sub.

Explore how streaming data works in AWS with Kinesis Data Streams, Firehose, Analytics and Video Streams, including shards, records, partition keys and real-time processing.

Explore EC2 elastic compute cloud, AWS's virtual servers, covering instance lifecycles, AMIs, instance types, security groups, key pairs, user data, and pricing models.

Master elastic load balancing in AWS, including classic, application, and network load balancers, their listeners and target groups, and auto scaling for scalable web apps.

Explore Elastic Beanstalk to deploy and scale web applications with load balancing, auto scaling, and managed updates, using web server and worker tiers, environments, and application versions stored in S3.

Orchestrate microservices with ECS and Fargate, deploy Docker images via task definitions and services, and manage IAM roles, placement, and dynamic port mapping.

Learn how CloudFront delivers global content with edge locations and low latency, secures access via signed URLs or cookies, and uses Route 53 for DNS routing and alias records.

Learn to implement devops in AWS with CodeCommit, CodeBuild, CodePipeline, CodeDeploy, automate continuous integration, and use infrastructure as code with CloudFormation, TerraForm, and Sam, including blue-green and canary deployments.

Explore how CloudFormation automates infrastructure deployment using JSON or YAML templates, provisioning resources like VPC, subnets, EC2, RDS, and more.

learn how the serverless application model (sam) streamlines building and deploying serverless apps with infrastructure as code, resources like Lambda, API gateway, DynamoDB, and CloudFormation, plus sam cli workflows.

Master AWS serverless concepts, including event source mapping for Lambda, ALB integration, VPC access, and AppSync data sync, plus Step Functions versus SWF for workflows.

Explore AWS monitoring and governance services, including CloudTrail, Config, and CloudWatch, plus tracing with X-ray to analyze metrics, logs, alarms, events, and annotated traces across microservices.

Master the AWS CLI to run commands, manage credentials with aws configure, and use profiles, region, and output formats. Explore STS for temporary credentials, assume role, and web identity federation.

Learn to implement cross-origin resource sharing, externalize configuration with environment variables and Parameter Store, manage Secrets Manager, and apply caching strategies using AWS ElastiCache and DAX.

Explore the AWS well-architected framework to build secure, high-performing, resilient, and efficient applications, guided by five pillars: operational excellence, security, reliability, performance efficiency, and cost optimization.
