Re-architecture of AWS Environment, Build infrastructure as a code, Implementation of security controls & Infrastructure Managed services

ServiceMax is one of the world’s leading providers of field service management software for equipment manufacturers and service providers. ServiceMax’s AWS cloud-based SaaS solution processes more than a million work orders per month, scheduling more than 300,000 technicians worldwide and managing 150 million customer devices. Trianz was selected to re-architect and manage ServiceMax’s existing Amazon Web Services (AWS) environment to achieve higher levels of performance, security and availability.

The Business Challenge

The client was seeking a partner to explore the use of a cloud platform as a key strategy to address infrastructure growth needs. In the given context, Trianz has initiated assessment of the Amazon Web Services (AWS) Cloud platform with the client to help explore the possibilities of executing a time bound, object-oriented, proof-of-concept based deployment on AWS.

The client also wanted to build a dependable, robust and secure technology infrastructure on AWS that could:

  • Facilitate script automation to eliminate manual process-related errors
  • Reduce the cost of operations, as more bandwidth means more complexity and increased operational expense
  • Minimize downtime to prevent revenue loss as network outages significantly disrupt business operations, adversely impacting customer loyalty
  • Protect enterprise data to tackle the ever-increasing threat of cyberattacks and data breaches incidents
  • Scale the network to equip it for future 'on-demand' growth to manage changes in real-time
  • Enhance network performance through agile applications that can handle dynamic bandwidth needs and network topology changes

Technology Components

AWS

  • Amazon VPC
  • Amazon Route53
  • Amazon CloudFront
  • Elastic Load Balancing
  • Amazon EC2 & EC2 Autoscaling
  • AWS Lambda
  • Amazon s3
  • Elastic Block Store
  • AWS IAM
  • Amazon GuardDuty

The Approach

In order tore-architect and manage the client’s existing Amazon Web Services (AWS) environment., here’s what we did:

  • Redesigned the infrastructure with AWS best practices including 'Infrastructure as Code.
  • Developed Terraform modules to deploy the entire infrastructure, making it scalable and flexible.
  • Introduced hub-spoke architecture and deployments for increased resilience.
  • Introduced best practices in security such as boundary defense, CIS hardening, endpoint security, credential management, MFA, monitoring, auditing, logging, certificate and key management and vulnerability management.
  • Implemented blue/green method of application rollouts using Terraform and Jenkins pipelines.
  • Implemented Single Sign-On using Jumpcloud for all eligible services.

Transformational Effects

  • Better performance with improved efficiency & high availability
  • Improved application rollout
  • Easy to redeploy environments using infrastructure-as-a-code for CI/CD as well as disaster recovery
  • Optimized costs and improved SLAs, while meeting customer security requirements
  • Reduced Downtime & Improved Efficiency:
    • Reduced 80% of downtime with the blue/green method of application rollout
    • Reduced the timespan to spin up new application PoPs from 1 month to 1 week
  • Enhanced Security:
    • Passed external & internal audits
  • Operations Excellence:
    • Reduced false alarms
    • Auto-remediated common anomalies
