Erlang
A battle-tested programming language designed for the concurrency demands of modern computing.
Quicker updates, less physical infrastructure, higher uptime
Erlang is a programming language designed with high availability in mind. It’s used to build massively scalable soft real-time systems with requirements on high availability. As a result, it is the best programming language to solve many of today’s computing problems. Many of the worlds largest banking, e-commerce, social media platforms, FinTech and HealthTech companies depend on Erlang-based technologies to power their tech stack.
If you have a system that handles large amounts of concurrent users, adopting Erlang can help you significantly reduce your lines of code and increase your scalability simultaneously. The result is less vulnerabilities, an easier system to maintain, reduced physical infrastructure and more users with higher system uptime.

Bet365 case study
We helped Bet365 move from Java to Erlang to deliver smooth service to 22 million players.
Discover how we improved the reliability, quality and security of their system.
Erlang has become an essential technology in our toolkit. It is helping us to create reliable, fault-tolerant systems that can be scaled incrementally to meet the growth in our business.

The Payments Switch is highly fault tolerant yet offers massive concurrency. This is critical to payment transactions. At the same time the development project cooperation with Erlang Solutions was agile and responsive, giving us the opportunity to explore the possibilities to support our clients.
Adam Kennedy
I spoke with two CTOs I know who utilize Erlang and they both recommended Erlang Solutions. They were able to come in with their expertise, help us establish best practice and give us confidence that going forward our systems would be efficient and reliable.

Faster
With 4 to 20 times less code required your solutions will be delivered in less time. Smaller systems are also easier to manage, maintain and update.
Safer
Solutions on the BEAM VM have 10-100 times fewer vulnerabilities in the CVE (Common Vulnerabilities and Exposures) database than other languages like PHP, JavaScript, Java
More users
Erlang and Elixir have the scalability and fault-tolerance mechanisms that handle millions of parallel users during peak hours AND withstand denial-of-service (DDoS) attacks.
Reliable
Systems built on the BEAM VM are famous for their error handling, reliability and fault-tolerance. There are real, long-term in-production examples of systems with 99.999% uptime.
Sustainable and cost-effective
Smaller codebases also lead to a reduction in the needs for physical infrastructure with some clients being able to downsize from 150 servers to 5 while growing their user base.
