AWS Secrets Manager vs Systems Manager Parameter Store

2020-07-08T03:02:55+00:00

AWS Secrets Manager vs Systems Manager Parameter Store Managing the security of your applications is an integral part of any organization especially for infrastructures deployed in the cloud. One aspect of application security is how the parameters such as environment variables, database passwords, API keys, product keys, etc. are stored and retrieved. As a best practice, secret information should not be stored in plain text and not be embedded inside your source code. It is also recommended to set up an automated system to rotate passwords or keys regularly (which is easy to forget when you manage keys manually). Managing [...]

Step Scaling vs Simple Scaling Policies in Amazon EC2

2020-06-23T03:49:44+00:00

Step Scaling vs Simple Scaling Policies in Amazon EC2 Amazon’s EC2 Auto Scaling provides an effective way to ensure that your infrastructure is able to dynamically respond to changing user demands. For example, to accommodate a sudden traffic increase on your web application, you can set your Auto Scaling group to automatically add more instances. And when traffic is low, have it automatically reduce the number of instances. This is a cost-effective solution since it only provisions EC2 instances when you need them. EC2 Auto Scaling provides you with several dynamic scaling policies to control the scale-in and scale-out events. [...]

Amazon EC2 Auto Scaling Lifecycle Hooks Amazon EC2 Auto Scaling allows you to scale-out or scale-in your EC2 instances automatically based on policies you configured in response to changing demand on your application. Auto Scaling Groups lets you set a minimum and maximum number of EC2 instances to automatically resize your cluster based on a defined schedule or instance metrics such as CPU utilization, network traffic, etc. This is an excellent way to cut costs and make sure you have the correct number of instances since traffic on your application fluctuates throughout the day. Auto Scaling Lifecycle Hooks As your [...]
