Introduction

K&C’s client, a major online gaming software supplier that offers cutting-edge, value-added solutions to the industry's leading operators, decided to extend its in-house R&D team with a dedicated development team tasked with building strong competence center for Liferay solutions. The team in question was provided by K&C, with us forming an elite agile development unit from the crack troops based in our nearshore offices in Ukraine, Poland and Bulgaria, expertly martialled by our Germany-based management.

K&C has been providing ongoing support to the client since 2012, helping to hire more than 100 highly skilled agile developers for multiple development project across technologies such as Angular, React, Web, Cloud, AWS, Kubernetes, Microservices, DevOps and DevSecOps (DevOps Security). One of the of the key projects K&C provided a dedicated agile team to work on was an improvement in the performance of the client’s core online gaming platform.

Project highlights

40x
Improved portal performance by 40 times
20%
20% average CPU load under 400K rpm
10x
10x boost via using CDN

The Challenge

Consistently reliable website performance is an important part of any great user experience. For large online platforms with millions of users it is even more critical and poor response time is unacceptable.

Consistently reliable website performance is an important part of any great user experience. For large online platforms with millions of users it is even more critical and poor response time is unacceptable.
CLIENT'S REQUEST:
Maintain portal stability under high loads, guarantee fast response time, including during offline

99 % success rate
events
The application was built on Liferay, an open-source platform for the development of collaboration portals. Despite Liferay being one of the most popular, high-performing and scalable technologies, optimization of several performance-specific processes was still required in order to improve user experience.
Platform characteristics
100 000+ users
12 million transactions/hour
16 nodes in cluster
20x times more traffic during some offline gambling events

K&C approach

K&C’s dedicated nearshore team applied its deep technical expertise to first gain a thorough understanding of the client’s business needs and requirements and subsequently find the optimal solution. To define the project scope, we had to carry out a detailed evaluation of the existing app infrastructure:
  • Hardware assessment
  • Review of the deployment processes
  • Log files and configurations review
  • Existing software architecture analysis
  • Load testing and database/network/web page profiling
Liferay Portal Performance Tuning Services: Approach
Following deep evaluation and analysis our team identified major gaps and dependences that were the root cause of an inappropriate web portal performance.

Solution

A considerable boost in performance obtained without Liferay core changes:
Liferay Portal Performance Tuning Services: Solution

Back-end solutions implemented

  • Liferay core modifications and different treatments
  • Liferay’s Search Engine Configuration – replacing internal Lucene with external Solr / ElasticSearch
  • Advanced CDN support
  • Cluster configuration, including JGroups tuning
  • Scaling and high availability
  • Application code profiling to find bottlenecks in custom portlets or extensions
  • Distributed cache replication configuration based on RabbitMQ message broker
  • Push notification system with RabbitMQ message broker
  • Gradle as a build tool

Front-end solutions implemented

  • Ultra-lightweight page size
  • Remastering of UI and themes to minimize page load time
  • Custom JS and CSS barebone bundles, sprites
  • Using browser Local Store for rare changes

Results

After our dedicated agile team had analysed the client’s web solution, processes and IT environment they applied a smart and intuitive load testing environment combined with deep Liferay’s core tuning. The result was K&C managed to achieve the following notable improvements in the core gaming portal’s performance.

40x improvement in overall portal performance

Strong service responsiveness during offline events maintained

20% average CPU load under 400K rpm achieved

K&C hire developers in Ukraine, Poland and Bulgaria to form our dedicated teams and team extensions. Their agile development skill set, expertly co-ordinated under Germany-based management have delivered hundreds of projects like Bosch’s Drivelog.de portal at an attractive nearshore cost. Specialists in technologies such as Angular, React, Web, Cloud, AWS, Kubernetes, Microservices, DevOps and DevSecOps (DevOps Security Integration), our German-standard software engineering has helped realise thriving projects developed from organisations ranging from start-ups to enterprise-level organisations.
