Longest Prefix Match: Understanding Advanced Concepts in VPC Peering

2023-08-14T02:40:31+00:00

VPC Peering Basics In AWS, a Virtual Private Cloud (VPC) peering connection is a networking connection between two VPCs which allows you to route specific traffic between them using either private IPv4 addresses or IPv6 addresses. A VPC peering connection can be created between your own VPCs, or alternatively, a VPC in another AWS account. You can also create an inter-region VPC peering connection where the VPCs are located in different AWS Regions. Amazon EC2 Instances in either VPC can communicate with each other freely as if they are within the same network. One example of VPC Peering is the [...]

How to invalidate API Gateway Cache

2021-05-03T13:34:08+00:00

To invalidate an existing cache entry of a request and retrieve the latest data from the integration endpoint, one must send the request together with the Cache-Control: max-age=0 header. If the recipient is authorized to communicate directly to the integration endpoint, then the integration endpoint will respond with the latest data for the request. This also replaces the existing cache entry with the new response. The IAM Policy that grants a client to invalidate the cache follows: {   "Version": "2012-10-17",   "Statement": [     {       "Effect": "Allow",       "Action": [         "execute-api:InvalidateCache"       ],       "Resource": [ "arn:aws:execute-api:region:account-id:api-id/stage-name/GET/resource-path-specifier"       ]     }   ] }    An alternative option [...]

Top 5 Free AWS Review Materials

2021-06-26T13:32:00+00:00

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 $30 to $38 per month or [...]

Calculating the Required Read and Write Capacity Unit for your DynamoDB Table

2021-05-04T09:10:25+00:00

Read Capacity Unit On-Demand Mode When you choose on-demand mode, DynamoDB instantly accommodates your workloads as they ramp up or down to any previously reached traffic level. If a workload’s traffic level hits a new peak, DynamoDB adapts rapidly to accommodate the workload. The request rate is only limited by the DynamoDB throughput default table limits, but it can be raised upon request. For on-demand mode tables, you don't need to specify how much read throughput you expect your application to perform. DynamoDB charges you for the reads that your application performs on your tables in terms of read request [...]

Kinesis Scaling, Resharding and Parallel Processing

2023-03-20T03:29:22+00:00

Kinesis Resharding enables you to increase or decrease the number of shards in a stream in order to adapt to changes in the rate of data flowing through the stream. Resharding is always pairwise. You cannot split into more than two shards in a single operation, and you cannot merge more than two shards in a single operation. The Kinesis Client Library (KCL) tracks the shards in the stream using an Amazon DynamoDB table, and adapts to changes in the number of shards that result from resharding. When new shards are created as a result of resharding, the KCL discovers [...]

DynamoDB Scan vs Query

2023-01-30T13:33:00+00:00

Scan The Scan operation returns one or more items and item attributes by accessing every item in a table or a secondary index. The total number of scanned items has a maximum size limit of 1 MB. Scan operations proceed sequentially; however, for faster performance on a large table or secondary index, applications can request a parallel Scan operation. Scan uses eventually consistent reads when accessing the data in a table; therefore, the result set might not include the changes to data in the table immediately before the operation began. If you need a consistent copy of the data, as [...]
