Logging Using awslogs Log Driver in Amazon ECS

2021-05-04T09:25:50+00:00

Monitoring and logging can be as important as developing and deploying applications. Imagine managing an enterprise-level distributed application that runs on hundreds of containers. You must place your containers cleverly on instances to achieve a certain level of resilience and performance. On top of that, you would want to have visibility into CPU and memory usage so you’ll have an idea which task/tasks are resource-hungry at a given time. You may also want to check the disk space of your instance and see if you still have enough storage for your application. Fortunately, monitoring distributed applications hosted in AWS has [...]

Managing Amazon GuardDuty Security Findings Across Multiple Accounts

2023-02-03T10:16:00+00:00

In our previous article, we discussed how GuardDuty can help organizations monitor their workloads and  AWS accounts from malicious activities and how to monitor findings with Amazon CloudWatch Events. Imagine that your organization has multiple AWS accounts for different workloads, teams, and projects. With every account, you need to monitor GuardDuty findings individually. It will be quite difficult for your security team to monitor these findings with their constant switching between AWS accounts.  Amazon GuardDuty supports the consolidation of these findings to one AWS account. For example, your organization has 10 AWS accounts. All you have to do is to [...]
