Case Study Law of the Jungle: Applying modern DevOps concepts in AWS

Updated: Jul 3


About Law of the Jungle

Law of the Jungle solutions overcomes the gap between the business aim and the legal constraint for marketing compliance. Their solution increases the productivity for effective compliance, getting more done and reducing time to market. Bringing agile methodologies to marketing teams and guiding them through the compliance aspect using artificial intelligence on AWS.


LOTJ promotes that its clients can turn marketing compliance into a competitive advance.


The Business Challenge

Law of the Jungle was already running workloads in AWS, however with lots of configuration management and complex deployments. Therefore, LOTJ aimed to reduce time to market by reducing environment complexity. Another challenge which was brought to the table was how to improve knowledge and information management, making the best use of that.


To achieve it, DNX Solutions was engaged by LOTJ to support these challenges. Together was decided to push immutability concepts on a new AWS platform which uses Infrastructure as a Code (IaC) process improving knowledge and information management. To build a demonstration environment for potencial LOTJ' customers will enable the sales team to reach out more people.


DNX Solution

Before start running the project, DNX’s team evaluated the organisation’s requirements also plunged into the processes through DNX’s DevOps approach which drives the team over the DevOps journey while building a perfect foundation, standardising and automating processes, and use the technologies to deliver applications quickly and reliably.


Our solution for this scenario is to modernise the current java microservices leveraging Docker containers and orchestrate them using AWS Elastic Container Service clusters.


Focused on reduce configuration management, the applications were modernised applying 12-factor concepts, also improving the continuous deployment by using environment variables stored in SSM Parameter Stores. The ECS Service uses task definitions, it is a powerful tool to achieve immutability and run multiples containers across the cluster instances sharing the same file system, where EFS have mount targets across the different availability zones.


AWS Foundation

As most of the projects, at DNX we start deploying our AWS platform as it is the first layer of modernisation, the AWS Well-Architected Foundations built by DNX applying affective infrastructure code patterns, brings instant value to our clients, as it covers essentials aspects to an organisation that has DevOps culture incorporated into their DNA.

Once we have the terrain prepared we start the modernisation phase, where DNX team prepare the microservices to the new cloud environment. With immutable concepts applied since the building stage into the Bitbucket pipelines to the applications production stage in AWS, the configuration management is eliminated. There is no need to access production or staging servers once they are up and running and if an exceptional need appears, the connection is secured executed by SSM Session manager as every EC2 instance has its agent installed.


It is important to mention that DNX uses spot instances for the ECS cluster, generating 70% cost reduction on average. Also, our solution implements a well-architected account topology in AWS. Where Law fo the Jungle can have testing and development environments identical to production with reduced or similar compute power. Adding a management account facilitates security and audit aspects, keeping non-prod and production environments secure and high available even during an audit process or security tests.

Continuous Delivery:

The container built during the building stage will be deployed across AWS accounts and environments. It ensures that the same application that is tested is deployed to production, providing consistency during bug fixes and new releases:



Steps:

  • Application build

  • Application Docker Build and Push to ECR

  • Application ECS Blue-Green Deployment using AWS Code Deploy

  • Automatic deploy to QA / Staging

  • Automatic deploy to production with manual approval

It is worth to mention that during the whole project, DNX executes knowledge transfer sections with DNX AWS certified professionals to Law of the Jungle. DNX believes that is the right way to build a healthy relationship with customers and partners.


Some of the AWS Services provisioned:

  • AWS ECS

  • AWS Elastic File System (EFS)

  • System Manager

  • CloudTrail

  • Aurora Cluster

  • Cloud Watch

  • Code Deploy

  • AWS Config


Conclusion

That is a stress-free environment built by DNX Solutions. A safe place for experimentations and faster new features time to market, as LOTJ solutions promote to their customers, DNX provided the conditions and tooling in AWS to apply modern and efficient DevOps practices in the organisation. As a result, they started deploying 2x more new features to the LOTJ users. Another benefit is a new demo environment where potential customers can try the solution in a secure and isolated approach on AWS.


To help LOTJ with the knowledge management challenge, after AWS foundation phase and knowledge transfer sections with DNX team, the company has started to have all the knowledge in the code, reducing time on on-boarding of new team members.
