Transformation of SleevesUp - Sorted Legacy Technology to Modern Automated

& Robust Infrastructure

Sorted Services is a real estate app of SleevesUp, that helps end users manage their bill

payments right from the time of moving into a rented property. This one-stop shop mobile app

helps users pay all their bills including house rents, electricity, broadband, water, gas and other

utilities on a single mobile app. HashedIn helped SleevesUp by re-engineering their legacy

application which was prone to app crash, processing failures, lag, etc.

About SleevesUpSleevesUp is a co-working space for ideas, startups and enterprises. It brings together a broad

network of skills and experience, including Strategy, Business Growth, CX Design and Software

ObjectiveSleevesUp wanted Sorted App to be revamped in order to make it scalable, fault tolerant, reduce cost, build to deploy time and dependency on Fargate. The key objectives of the project included,

1. Reduce cost by moving away from AWS Fargate2. Build CI-CD pipeline for web portal, Android and iOS version. 3. Leverage best of AWS and 3rd party tools & services to improve control over containers 4. Incorporate services to monitor, user and service usage5. Generate alerts, reports and logs for audit

HashedIn’s SolutionOur solution involved use of AWS ECS instead of Fargate, to increase control over containers and reduce cost. We leveraged Buildkite to implement CI/CD pipeline for web portal and Bitrise to achieve the same in mobile app. Amazon Cloudwatch was used for the monitoring of activities of AWS services and DataDog to monitor container services. We leveraged RDS Postgresql replacing the legacy MS-SQL to benefit from of multiple DR, fault tolerant and resilient infrastructure. Terraform was used to implement infrastructure-as-a-code to quicken the infra set-up process. Production environment artifacts and logs generated were stored in S3. We leveraged SES to send across multiple services and application to send email notifications.

Key HighlightsIntroduced DevOps process across different environment with industry leading toolsAny code commit in bitbucket triggered a new build in buildkite or bitrise, which will deploy build in dev for running unit and integration testing. The same build would be moved on to QA and subsequently to Production environmentHashicorp’s Consul and Vault were used to store secrets

OutcomesReduction in license cost by upto 20% by leveraging free and low cost services/toolsTime taken for build to deploy reduced from 2 weeks to 2 hoursDeployment of application in Amazon ECS with container registry and autoscaling services helped in auto-scaling the application according to the traffic spikeDataDog monitors and sends alerts to the registered email addresses which helps in understanding the cause for an issue without logging in to it. This also helped in proactive resolution of issues within defined SLAs
