PurposePurpose of this post is, to achieve a knowledge enrichment for myself. It’s more than a repetition, I also add some findings to the content I learned from additional sources and I get some practice using draw.io for architecture visualization. And as well for free, some Use Cases for training using my AWS Account! TopicBelow […]
Secure your data, secure your network. To ensure security from the very first beginning each customer choose the Availability Zones for his cloud to ensure the replication of the data, only mirrored in the selected Region/s. An other security aspect is the separation in Public Subnet and Private Subnet. Everything for the Public Subnet has […]
Inbound Access. From Public Internet and Datacenter This example above shows, how Security Groups provide aditional control of the access to diffrent servers. The Security Groups have only „allow“ rules an dno „deny“ rules. The default value is always no inbound traffic is allowed and all outbound traffic is allowed. The rules allow responses from […]
Improve the initial project. „You can’t fix what you don’t monitor!“ In this very simple architecture example we use an EC2 instance, placed in the center. We mount EBS volume as a network block store for database files. The instance store (ephemeral) is used only to support high performance cache and is local block store, […]
You only can control, what you measure! So CloudWatch is a possibility for monitoring your resources and applications running on AWS by collecting and tracking standard and custom metrics, like log files. If the defined alarm state is achieved, CloudWatch Alarm sends via SNS e.g. a email notification to the ops team, automatically EC2 starts […]
Fleetmanagement, EC2 Auto Scaling. The idea of EC2 Auto Scaling groups is to ensure automated the required compute capacity. Auto Scaling independently detect if a failure occurs in one or more instances and an automated replacement takes place. The Maximum, Minimum and the Desired capacity will defined initially e.g. via the Management Console. If for […]
Elastic Load Balancer: Application/ Network Automatic distribute traffic across multiple targets. The example shows how to use Load Balancer for Network and Application use cases. The service provides log files to CloudWatch for measurement and monitoring purposes. The service stops sending traffic to a non responding instance, so it’s also a good tool for health […]
The topics before focused on how to build individual servers in the cloud, set up data volumes, network environments. Next is deploying database services, this is a whole architecture tier of an application! E.g. you can deploy a master and a standby DB in two regions in a „off the shelf way.“ In EC2 instance […]
Amazon Route 53 is a highly available and scalable Domain Name System (DNS) web service. The core functionality is register your domain names, route internet traffic to the resources for your domain, check the health of your resources. The main purpose is to have a component extremely reliable and cost optimized to route end users […]
AWS CloudFormation: Model and provision all your cloud infrastructure resources. AWS CloudFormation is a model and provision for all your cloud infrastructure resources used for automated deployment. Different environments like e.g. trainings environments or A/B-test environments are quick deployed. They are based only on a script (template in either YAML or JASON) load and fire […]
