ABOUT NATVISA

Natvisa have been functioning in this industry for many years, and although they have gone through quite a few name changes, but services however, remained exceptional. Since 2014, we have made it our mission to ease the process of acquiring travel visas and have continued on the path of improving and evolving our services.

To offer a better service to our customers, we decided for digital transformation in cloud environment and selected AWS for a scalable, secure and high availability platform.

CUSTOMER CHALLENGE

To highlight precisely about the challenge, initially we are running our application on a single ec2 instance, however there were lot of problems as the server won’t take the workload. The challenges that we faced were enormous and some of points are that there was no redundancy and no fault-tolerance with our application. Some of the following queries were

• Application migration from PHP to Next.js.
• Stable, Secure and Fast Architecture to run a NextJS Application.
• To use Nginx as proxy.
• To make use of RDS.
• Going Global: How to Scale and Maintain High Performance and Low Latency.
• Easy to Deploy new code changes.
• Automation for Development Team.

We got in touch with Geeks Solutions as they were managing our infrastructure and we have experienced their expertise in managed IT solutions. They proposed with the following solutions to address all those challenges which we eventually did.

PARTNER SOLUTION

Being an Amazon partner and having 15+ years background as managed service provider in the field of server management, we took our experience along with our AWS expertise to deliver the best.

Geeks Solutions has a track record of building Containerised Orchestration and Kubernetes-based deployments on everything from bare metal to virtualized private data-centers and the cloud.

We suggested and client chose KOPS. Kops is short for Kubernetes Operations (also spelled kops or kOps), a set of tools AWS offers for installing, operating, and deleting Kubernetes clusters. You can also use it to roll out an upgrade of an older version of Kubernetes to a new one and manage cluster add-ons. After creating a cluster, you can use the usual kubectl CLI to manage resources.

TECHNOLOGY STACK

• Amazon EC2 Auto Scaling is used to horizontally spin on-demand EC2 instances to handle high traffic and load.
• Amazon Elastic Load Balancer is used to distribute traffic to the EC2 instances in Autoscaling
• Amazon S3 bucket is used for storing static and dynamic content
• Amazon CloudWatch is used to monitor various aspects of the AWS infrastructure and facilitate other services.
• Amazon Aurora MySQL is used for application database hosting with multi-AZ environment.
• Amazon Elastic File System is used for Persistent Volumes in Kubernetes.
