Elastic Container Service (ECS) vs Lambda

2021-08-31T08:13:07+00:00

Amazon EC2 Container Service (ECS) AWS Lambda Amazon ECS is a highly scalable, high performance container management service that supports Docker containers and allows you to easily run applications on a managed cluster of Amazon EC2 instances. ECS eliminates the need for you to install, operate, and scale your own cluster management infrastructure. With ECS, deploying containerized applications is easily accomplished. This service fits well in running batch jobs or in a microservice architecture. You have a central repository where you can upload your Docker Images from ECS container for safekeeping called Amazon ECR. Applications in ECS can be written [...]

Service Control Policies (SCP) vs IAM Policies

2021-08-31T09:00:40+00:00

Service Control Policies (SCP) IAM Policies SCPs are mainly used along with AWS Organizations organizational units (OUs). SCPs do not replace IAM Policies such that they do not provide actual permissions. To perform an action, you would still need to grant appropriate IAM Policy permissions. Even if a Principal is allowed to perform a certain action (granted through IAM Policies), an attached SCP will override that capability if it enforces a Deny on that action. SCP takes precedence over IAM Policies. SCPs can be applied to the root of an organization or to individual accounts in an OU. When you [...]

S3 Transfer Acceleration vs Direct Connect vs VPN vs Snowball Edge vs Snowmobile

2021-08-25T10:12:14+00:00

S3 Transfer Acceleration (TA) AWS Direct Connect AWS VPN Amazon S3 Transfer Acceleration makes public Internet transfers to S3 faster, as it leverages Amazon CloudFront’s globally distributed AWS Edge Locations. There is no guarantee that you will experience increased transfer speeds. If S3 Transfer Acceleration is not likely to be faster than a regular S3 transfer of the same object to the same destination AWS Region, AWS will not charge for the use of S3 TA for that transfer. This is not the best transfer service to use if transfer disruption is not tolerable. S3 TA provides the same security [...]

Application Load Balancer vs Network Load Balancer vs Gateway Load Balancer

2021-09-28T06:36:16+00:00

Common features between the load balancers: Has instance health check features Has built-in CloudWatch monitoring Logging features Support zonal failover Supports connection draining Support cross-zone load balancing (evenly distributes traffic across registered instances in enabled AZs) Resource-based IAM permission policies Tag-based IAM permissions Flow stickiness - all packets are sent to one target and return the traffic that comes from the same target.

AWS Elastic Beanstalk AWS CloudFormation AWS Elastic Beanstalk makes it even easier for developers to quickly deploy and manage applications in the AWS Cloud. Developers simply upload their application, and Elastic Beanstalk automatically handles the deployment details of capacity provisioning, load balancing, auto-scaling, and application health monitoring. This platform-as-a-service solution is typically for those who want to deploy and manage their applications within minutes in the AWS Cloud without worrying about the underlying infrastructure.  AWS Elastic Beanstalk supports the following languages and development stacks: Apache Tomcat for Java applications Apache HTTP Server for PHP applications Apache HTTP Server for Python [...]

Amazon Simple Workflow (SWF) vs AWS Step Functions vs Amazon SQS

2021-08-31T08:39:04+00:00

Amazon Simple Workflow (SWF) A web service that makes it easy to coordinate work across distributed application components. In Amazon SWF, tasks represent invocations of logical steps in applications. Tasks are processed by workers which are programs that interact with Amazon SWF to get tasks, process them, and return their results. The coordination of tasks involves managing execution dependencies, scheduling, and concurrency in accordance with the logical flow of the application. AWS Step Functions A fully managed service that makes it easy to coordinate the components of distributed applications and microservices using visual workflows. You define state machines that describe [...]

CloudWatch Agent vs SSM Agent vs Custom Daemon Scripts

2021-08-31T08:00:41+00:00

CloudWatch Agent SSM Agent (AWS Systems Manager) Custom Daemon Scripts CloudWatch agent allows you to collect more system-level metrics from your EC2 and on-premises servers than just the standard CloudWatch metrics. It also enables you to retrieve custom metrics from your applications or services using the StatsD and collectd protocols. StatsD is supported on both Linux servers and servers running Windows Server. collectd is supported only on Linux servers. You can use CloudWatch agent to collect logs from your servers and send them to CloudWatch Logs. Metrics collected by the CloudWatch agent are billed as custom metrics. You can install [...]

S3 Pre-signed URLs vs CloudFront Signed URLs vs Origin Access Identity (OAI)

2021-08-31T08:55:03+00:00

S3 Pre-signed URLs CloudFront Signed URLs Origin Access Identity (OAI) All S3 buckets and objects by default are private. Only the object owner has permission to access these objects. Pre-signed URLs use the owner’s security credentials to grant others time-limited permission to download or upload objects. When creating a pre-signed URL, you (as the owner) need to provide the following: Your security credentials An S3 bucket name An object key Specify the HTTP method (GET to download the object or PUT to upload an object) Expiration date and time of the URL. You can control user access to your private [...]
