Challenge To improve business outcomes and to prevent downtimes of the existing e-commerce application built on top PHP framework and AWS Aurora as a back end, the client requested Romexsoft to build proactive monitoring solution for the existing AWS production environment to resolve issues before they become critical. The challenge was to build a cost-effective monitoring solution for log, infrastructure, application and cloud services monitoring, that monitoring infrastructure must be cheaper than using Splunk and show more information than Splunk. Another challenge was to collect logs from Rancher and all containers that exist in it with minimum load to the Rancher server and instances. Solution Being a certified AWS consulting partner, Romexsoft did professional expertise of current client’s environment and decided to choose EFK cluster (Elasticsearch, FluentD and Kibana) for log monitoring, Zabbix server for infrastructure and services monitoring. To visualize metrics via dashboards the Grafana was chosen. That full-featured interactive dashboard helps observe the whole infrastructure in one place.  The solution is built on top of 3 t3.medium instances for EFK cluster and 1 t3.small instance for Zabbix server and Grafana. Grafana holds the separate dashboards with the information from EFK cluster, Zabbix and CloudWatch. All tools we used are open source and highly flexible. Users can see all the information about the environment in one place (Grafana). EFK cluster written in the Docker-Compose and installed in the container is managed via Rancher like simple containers.

Challenge Application works with sensitive data of real users and limited access to it is required. From the one side, all passwords for database access, API tokens or any other sensitive configuration parameters for Production instances must be securely stored with limited access to them only by authorized personnel and removed from the application code level. On another side, there must be a way for effective development and testing on QA and Staging Environments. So strict separation of application’s codebase from its configuration is required here. Solution The huge variety of AWS services for different cases was a key reason the SavvyMoney team chose to work with AWS. Two of them AWS Systems Manager Parameter Store and CodeCommit were used to overcome this challenge.  Microservices architecture is built in Java Spring Boot framework. Each microservice is a separate REST API that performs required business logic and is running on EC2 instance in the Autoscaling Group. Launch Configuration has attached the IAM role with read-only access to the parameter store. So any sensitive parameter is known only for the application on startup and there is no way to see it. All sensitive configuration parameters from classic *.properties files are moved into the AWS Parameter Store and all *.property files with other parameters are moved into the CodeCommit. Spring Cloud Config service reads properties from CodeCommit and REST API application calls Spring Cloud Config for required properties on startup or on-demand refresh. Write access to Parameters store and CodeCommit has only authorized personnel. The following AWS services were utilized: Systems Manager Parameter Store CodeCommit EC2 in Autoscaling Group with Launch Configurations IAM Roles  Identity Access Management (IAM) Virtual Private Network (VPC) Benefits No access to sensitive data for a development team in Parameter Store and no way to see it being logged on the EC2 instance. The application code is separate from configurations. The same application with the same codebase can be launched in different environments: Staging, QA, Production. Separation parameters storage on Parameter Store and Code Commit allows better security, handling, and maintenance. There is a possibility to reload parameters from Code Commit on the fly without application rebuild or restart. There is a possibility to reload parameters from Parameter Store without application rebuild. Restart is required. Read More

Challenges Scale Development utilizes multiple technologies to advance their offering. Hosting the ava-touch app in the Heroku cloud, the company had to pay high prices for the services without getting enough benefits of it. At the same time, it would be less expensive and easier to manage the assets in AWS. AWS offers a wide variety of services that allow Scale Development to get desired elasticity, scalability and easy management of its cloud infrastructure.  Solution Being a certified AWS consulting partner, Romexsoft did professional expertise of ava-touch software and environment and quickly conducted a plan of migration to AWS with its infrastructure design. Implemented cloud system utilizes the following services: Domain Name System (Route53); Elastic Beanstalk Service (EBS); Elastic Container Service (ECS) with Autoscaling Configuration;  Elastic Load Balancer (ELB); Virtual Private Cloud (VPC),  Identity Access Management (IAM); Elastic Container Registry (ECR); RDS (PostgreSQL); Simple Storage Service (S3); Monitoring and Logging (Cloud Watch). DevOps Automation reflecting CI/CD processes was implemented by CodePipeline: CodeCommit; CodeBuild CodeDeploy Benefits As a result, the ava-touch apps environment was deployed in AWS without downtime. Scale Development pays 2-times lower price and a scalable system’s architecture made the application ready for high load. Romexsoft implemented Elastic Beanstalk Service (EBS) which gives SD opportunity easily manage its web app environment.  Romexsoft and SD continue working together. Romexsoft improves migrated web app source code. Moreover, the partner is going to develop other web apps implementing Serverless and Lambda AWS services there. Read More

Challenge The challenge was to build a cost-effective disaster recovery solution for the on-premise production environment without incurring the infrastructure expenses of a second physical site and to prepare for and recover from any negative event that could happen on main on-premise production environment. For instance, negative events that could happen with on-premise environments could be a hardware or software failure, a network or power outage, physical damage caused by fire or flooding, human error, or some other kind of significant disaster cause a negative impact on the business continuity. Solution To enable faster disaster recovery of the critical IT systems and recover from any event that has a negative impact on the Pragma IT business Romexsoft build Pilot Light Disaster Recovery Solution using reliable AWS cloud infrastructure. The pilot light Disaster Recovery scenario was chosen to keep a minimum version of the environment running in the AWS cloud.  The pilot light Disaster Recovery approach was delivered by configuring and running the most critical core elements of a customer’s system in AWS. When the time comes for recovery AWS infrastructure is rapidly provision a full-scale production environment around the critical one. Romexsoft did professional expertise of Pragma IT therapyBOSS on-premises environments and software components and build a fully functional pilot light DR environment on AWS to have most core elements of the production system already configured and running on AWS. The following AWS services were utilized: Elastic Block Storage(EBS); Elastic File System (EFS); Elastic Load Balancer (ELB); Virtual Private Cloud (VPC),  Identity Access Management (IAM); Amazon EC2 Simple Storage Service (S3) Benefits Leveraging the Pilot Light Disaster Recovery approach allows Romexsoft to build a cost-effective disaster recovery solution using a reliable AWS cloud. The AWS disaster recovery environment holds only the critical core of the customer system around which all other infrastructure pieces can quickly be provisioned to restore the complete system within 2 hours when the time comes.

Challenge Regression tests are required to be executed repeatedly with every new release or even with every code commit. This is a very time consuming routine process for QA engineers, therefore regression tests are the perfect candidates for test automation. To deliver better customer experience, the client decided to implement an efficient cost-effective automated testing approach to catch software bugs quickly, simplify release management and increase the testability of the whole system. Solution The infinite on-demand scalability and the technical capabilities of the AWS platform were key reasons thetherapyBOSS team chose to work with AWS.  Romexsoft did professional expertise of client SaaS platform, business logic, user flows, test scenarios and implemented the end-to-end Test Automation Solution running on cost-effective AWS infrastructure. Cost-effective AWS Infrastructure The following AWS services were utilized: Domain Name System (Route53) EC2 Elastic Beanstalk Service (EBS) with Elastic Container (ECS) Virtual Private Network (VPC) Identity Access Management (IAM) RDS Simple Storage Service (S3) Benefits We have integrated automated tests that produce test execution reports in easy to digest reporting format. The tests execute regularly and improve the quality of code and quality of refactored code. That helps to maintain consistency of existing business functionality for a project in general and for each separate developing feature. The solution saves a huge amount of time due to a parallel mode of test execution and that improves development speed and  CI/CD process in the software development lifecycle. The cost-effective AWS infrastructure was configured to run Test Automation Suite. The key benefits include: flexible and scalable AWS cloud infrastructure highly available and secure AWS infrastructure pay-as-you-go with no long-term commitment model Read More

Romexsoft developed Colorjive Lite 2.0 – an HTML5 application which allows users to perform full paint job in less than 10 minutes. The technology is based on the idea that color involves three participants: light, surface, and an observer. Integrating this technology gave Colorjive a competitive advantage as most color-matching software only takes the surface into account using an RGB calculation. For better  distinguishing between objects and greater use of color, The Paint Bucket algorithm has been used, which gave an opportunity to process images more quickly and increase user engagement. New design enhanced user experience, making the application easy to use and highly serviceable.
