IP Blocking: Use AWS WAF or NACL?

2023-08-14T02:45:24+00:00

What should you do if you identified a series of malicious attacks on your application coming from a specific IP address? Will you use AWS WAF to block that IP address or create a rule in your Network Access Control List to deny traffic from that IP? It is true that AWS WAF can filter web requests based on IP addresses, HTTP headers, HTTP body, or URI strings, to block common attack patterns, such as SQL injection or cross-site scripting. NACL, on the other hand, acts like a firewall for controlling traffic in and out of your subnets. If the [...]

Bookmarks Instrumenting your Node.js application Instrumenting your Java application Instrumenting your C# .Net application Instrumenting your Python application Instrumenting your Go application Instrumenting your Node.js application The AWS X-Ray SDK for Node.js provides middleware that you can use to instrument incoming HTTP requests. You need to add the SDK to your application’s dependencies, usually via package.json. Initialize the SDK client and add it to your application prior to declaring routes. var AWSXRay = require('aws-xray-sdk'); AWSXRay.setDaemonAddress('host:port'); app.use(AWSXRay.express.openSegment('MyApp'));       3. Lastly, use the SDK exceptions after declaring routes. app.get('/', function (req, res) [...]

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 [...]
