AWS Cloudformation: A Gift from AWS to IT Professionals
Whenever
we do a job/task in Personal or Professional life where we need to do 2 to 4
things to complete that job, lets say if we do gardening, for that we need to
perform some tasks like:
- Sweep Patio and Sidewalk
- Check for Weeds
- Cultivate some Soil
- Mulch some Soil
- Water some Plants that Need It
- Fertilize any Shrubs and Trees that Need Fertilizing
- Prune any Shrubs and Trees that Need Shaping
Obviously,
It takes time!. But If there is someone who can do these things like a robot
then we can save our time & hard work & spend that time in some other
tasks. It will be like a gift to us & we will be super happy.
In
the same way, AWS gave a gift to IT professionals in form of Cloudformation.
Now
the question is how Cloudformation is a gift for AWS IT professionals ?
Let
assume that there is a scenario where we need to launch a mid-level web
application, which has the following requirements:
- 2 instances with 4 GB RAM & 2 vCPUs
- Amazon Linux machine image
- Load Balancer
- 1 RDS
- 2 Elastic IPs
- Security group
- Authentication key
- Install Apache web server in both instances
- Configure apache server
If
we launch all the needed resources manually it would take time and would be a
hectic process. But Cloudformation made it easy. AWS
CloudFormation provides a common language for us to describe and provision
all the infrastructure resources in the cloud environment. CloudFormation
allows us to model and provision Infrastructure for our application by using a
text(template) file, in an automated and secure manner across all regions and
accounts. Cloudformation file is nothing but a Template file. AWS
CloudFormation uses these templates as blueprints for building AWS
infrastructure resources. We can write these templates in 2 simple languages:
- JSON
- YAML
Here
are the Template Anatomies which we need to mention as per need:
- AWSTemplateFormatVersion
- Description
- Parameters
- Mappings
- Conditions
- Transform
- Resources
- Outputs
There
is one more concept called Stack. When we use AWS CloudFormation, resources
that we are going to launch are managed as a single unit called stack. We can
create, update, and delete resources by creating, updating, and deleting stacks.
After
describing resources in Template and launching a stack, Cloudformation will
take care of everything, it means Cloudformation will launch all infrastructure
resources and perform all the operations what we have mentioned in Template.
But
IT Professionals are looking forward for Cloudformation automation too. It
means they do not want to perform the few steps of creating, updating or
deleting stacks manually. Here are some DevOps tools which will help to
automate these processes:
- Ansible
- Jenkins
- Puppet
- Chef etc.
