Top 5 Free AWS Review Materials

2019-10-08T03:25:28+00:00

Top 5 Free AWS Review Materials Currently, the cost of an AWS Certification exam starts from 150 USD for associate-level exams and up to a whopping 300 USD for professional-level and specialty-type exams. For some, this amount is negligible but to many IT professionals around the world, this amount is relatively expensive. The official AWS Practice Exam ranges from 20 to 40 USD, which you can only take once (unless you shell out another $20 or $40 again in order to retake it). On top of it, there are a lot of people who subscribe to online cloud learning providers which can range from [...]

AWS Migration Strategies – The 6 R’s

2019-10-14T08:58:15+00:00

AWS Migration Strategies - The 6 R's The 6 R’s Rehost (“lift and shift”) Move applications to AWS without changes. In large-scale, legacy migrations, organizations are looking to move quickly to meet business objectives. Applications may become easier to re-architect once they are already running in the cloud. This happens because the hard part, which is migrating the application, data, and traffic, has already been accomplished. Replatform (“lift, tinker and shift”) You are making a few cloud optimizations in order to achieve some tangible benefit without changing the core architecture of the application. Replatforming Tools Amazon Relational Database Service (RDS) [...]

AWS X-Ray

2019-10-04T06:42:47+00:00

AWS X-Ray AWS X-Ray analyzes and debugs production, distributed applications, such as those built using a microservices architecture. With X-Ray, you can identify performance bottlenecks, edge case errors, and other hard to detect issues. Concepts A segment provides the name of the compute resources running your application logic, details about the request sent by your application, and details about the work done. A segment can break down the data about the work done into subsegments. A subsegment can contain additional details about a call to an AWS service, an external HTTP API, or an SQL database. For services that don't [...]

AWS Step Functions

2019-10-14T08:11:53+00:00

AWS Step Functions AWS Step Functions is a web service that provides serverless orchestration for modern applications. It enables you to coordinate the components of distributed applications and microservices using visual workflows. Concepts Step Functions is based on the concepts of tasks and state machines. A task performs work by using an activity or an AWS Lambda function, or by passing parameters to the API actions of other services. A finite state machine can express an algorithm as a number of states, their relationships, and their input and output. You define state machines using the JSON-based Amazon States Language. A [...]

VPC Peering

2019-10-14T08:15:00+00:00

VPC Peering A networking connection between two VPCs that enables you to route traffic between them privately using private IPv4 addresses or IPv6 addresses. Instances in either VPC can communicate with each other as if they are within the same network. You can create a VPC peering connection between your own VPCs, with a VPC in another AWS account, or with a VPC in a different AWS Region (also called Inter-Region VPC Peering). A VPC peering connection is neither a gateway nor a AWS Site-to-Site VPN connection, and does not rely on a separate piece of physical hardware. There is [...]

AWS CodeBuild

2019-10-14T08:18:25+00:00

AWS CodeBuild A fully managed continuous integration service that compiles source code, runs tests, and produces software packages that are ready to deploy. Concepts A build project defines how CodeBuild will run a build. It includes information such as where to get the source code, which build environment to use, the build commands to run, and where to store the build output. A build environment is the combination of operating system, programming language runtime, and tools used by CodeBuild to run a build. The build specification is a YAML file that lets you choose the commands to run at each [...]

AWS CodePipeline

2019-10-14T08:19:53+00:00

AWS CodePipeline A fully managed continuous delivery service that helps you automate your release pipelines for application and infrastructure updates. You can easily integrate AWS CodePipeline with third-party services such as GitHub or with your own custom plugin. Concepts A pipeline defines your release process workflow, and describes how a new code change progresses through your release process. A pipeline comprises a series of stages (e.g., build, test, and deploy), which act as logical divisions in your workflow. Each stage is made up of a sequence of actions, which are tasks such as building code or deploying to test environments. [...]

AWS CodeDeploy

2019-10-14T08:23:43+00:00

AWS CodeDeploy A fully managed deployment service that automates software deployments to a variety of compute services such as Amazon EC2, AWS Fargate, AWS Lambda, and your on-premises servers. Concepts An Application is a name that uniquely identifies the application you want to deploy. CodeDeploy uses this name, which functions as a container, to ensure the correct combination of revision, deployment configuration, and deployment group are referenced during a deployment. Compute platform is the platform on which CodeDeploy deploys an application (EC2, ECS, Lambda, On-premises servers). Deployment configuration is a set of deployment rules and deployment success and failure conditions [...]

AWS Server Migration Service (SMS)

2019-10-14T08:28:35+00:00

AWS Server Migration Service (SMS) An agentless service for migrating thousands of on-premises workloads to AWS. This is the enhanced replacement of Amazon EC2 VM Import service. SMS orchestrates server migrations by: automating incremental replication of live server volumes to the AWS cloud allowing customers to schedule replications track the replication progress of a group of servers via Management Console Each server volume replicated is saved as a new Amazon Machine Image (AMI), which can be launched as an EC2 instance in the AWS cloud. If you are using application groupings, Server Migration Service will launch the servers in a [...]

AWS Database Migration Service

2019-10-14T08:31:19+00:00

AWS Database Migration Service AWS Database Migration Service supports homogeneous migrations such as Oracle to Oracle, as well as heterogeneous migrations between different database platforms, such as Oracle or Microsoft SQL Server to Amazon Aurora. You can use Database Migration Service for one-time data migration into RDS and EC2-based databases. You can also continuously replicate your data with high availability (enable multi-AZ) and consolidate databases into a petabyte-scale data warehouse by streaming data to Amazon Redshift and Amazon S3. Continuous replication can be done from your data center to the databases in AWS or the reverse. Replication between on-premises to [...]
