Specifying Triggers for AWS Config Rules

2021-05-04T07:37:33+00:00

AWS Config allows you to set “rules” to evaluate configuration settings on your AWS resources. The result of these rule evaluations are then displayed on the AWS Config web console. You can control the frequency of rule evaluations by AWS Config by specifying a trigger. A trigger refers to the method of evaluation for your config rules. There are two types of triggers to select from when creating a rule. 1. Configuration Changes When “configuration changes” is enabled, AWS Config will evaluate the config rule when specific resources are created, changed, or deleted. In simple terms, as the name implies, [...]

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

2021-05-04T08:41:17+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 [...]

Lifecycle Event Hooks in CodeDeploy

2021-06-13T23:57:27+00:00

Bookmarks Events Things To Consider In biology, life cycle refers to the series of stages or events that occur during an organism’s lifetime. Lifecycle also applies when automating software deployment on AWS CodeDeploy. Lifecycle event hooks refer to the series of events that describes how a deployment is accomplished. It allows you to control or perform actions on different stages of your deployment. In the traditional way, whenever you release a new feature for your application, you would have to manually disable the app and install the code. If the code resides in a repository [...]

Amazon EBS Multi-Attach

2021-05-04T09:20:35+00:00

Amazon Elastic Block Store or EBS is a durable block-based storage device that can be attached to your EC2 instance. AWS released a feature called Multi-Attach, which allows EC2 instances to share a single EBS volume for up to 16 instances and provide higher availability of your applications for Linux workloads. Each instance to which the volume is attached has full read and write permissions to the volume. The following are several considerations and limitations in using the Multi-Attach feature: Multi-Attach enabled volumes do not support I/O fencing. I/O fencing protocols control write access in a shared storage environment to [...]
