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

2024-01-18T07:05:33+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 [...]

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

2023-04-07T04:00:56+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

2023-04-08T04:26:22+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) vs Origin Access Control (OAC)

2023-08-30T13:09:41+00:00

  S3 Pre-signed URLs CloudFront Signed URLs Origin Access Identity (OAI) Origin Access Control (OAC) 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 [...]

Security Group vs NACL

2024-08-05T01:51:49+00:00

Security Group Network Access Control List Acts as a firewall for associated Amazon EC2 instances. Acts as a firewall for associated subnets. Controls both inbound and outbound traffic at the instance level. Controls both inbound and outbound traffic at the subnet level. You can secure your VPC instances using only security groups. Network ACLs are an additional layer of defense. Supports allow rules only. Supports allow rules and deny rules. Stateful (Return traffic is automatically allowed, regardless of any rules). Stateless (Return traffic must be explicitly allowed by rules). Evaluates all rules before deciding whether to allow traffic. Evaluates rules [...]

AWS CloudTrail vs Amazon CloudWatch

2023-06-27T01:45:43+00:00

AWS CloudTrail vs Amazon CloudWatch Cheat Sheet CloudWatch is a monitoring service for AWS resources and applications. CloudTrail is a web service that records API activity in your AWS account. They are both useful monitoring tools in AWS. By default, CloudWatch offers free basic monitoring for your resources, such as EC2 instances, EBS volumes, and RDS DB instances. CloudTrail is also enabled by default when you create your AWS account. With CloudWatch, you can collect and track metrics, collect and monitor log files, and set alarms. CloudTrail, on the other hand, logs information on who made a request, the services [...]

Amazon S3 vs Glacier

2023-04-07T03:45:20+00:00

Amazon S3 is a durable, secure, simple, and fast storage service, while Amazon S3 Glacier is used for archiving solutions. Use S3 if you need low latency or frequent access to your data. Use S3 Glacier for low storage cost, and you do not require millisecond access to your data. You have three retrieval options when it comes to Glacier, each varying in the cost and speed it retrieves an object for you. You retrieve data in milliseconds from S3. Both S3 and Glacier are designed for durability of 99.999999999% of objects across multiple Availability Zones. S3 and Glacier are [...]
