Safeguard existing investments whilst building a path to the future.
As your most important applications age they become increasingly expensive to run and may begin to fail user expectations. To maintain a competitive edge, these systems will need to be architected for the future to address evolving business needs.
Collaborative transformation.
Our approach to application modernization revolves around finding the most suitable and efficient pathway from legacy systems to truly modern, cloud-native applications. We believe in collaborative transformation. That means collaborative modernization too. We understand that rebuilding from scratch is not always the right approach.
But don’t worry if you don’t have an engineering team; we can provide all the expertise and work with you as business leaders to ensure that we modernize your platform.
Benefits
- Faster to Market: fourTheorem’s expertise in modern application development allows you to take ownership of services and make updates quicker.
- Reliable Applications: Fully automated continuous integration and deployment (CI/CD) lets you go faster without the risk.
- Innovation at Speed: Modular architecture reduces the risk of change in any individual service. Reduced maintenance = more time to experiment.
- Reduced Costs: Pay-for-value pricing of Serverless services can dramatically reduce running and maintenance costs and undifferentiated work.
The 4 pillars of a modern serverless application
Serverless Microservices
fourTheorem’s founders are leaders in microservices and serverless. We have published books and papers on these subjects and we have successful deployments under our belt.
What does this mean for you?
- Microservices means building your system from separate components that can be created and deployed independently.
- Microservices are now an established best practice. Done right, they give you faster development time, improved quality and vastly increased stability for your users.
- Serverless is the future of software. You build and deploy small, manageable components without thinking about servers or infrastructure.
- Serverless also means using managed services for things like user accounts, storage and analytics – the parts of your system that are not unique to your core business. This decreases costs significantly and gets you where you want to be much faster.
Continuous Integration & Deployment (CI/CD)
CI/CD is about automating every step in the build, test and deployment of your system. fourTheorem delivers on this practice for all our projects. Why is this an essential part of modern application development?
- Every time you commit completed code for a new feature, that code arrives in your production system without manual intervention.
- We avoid the risk posed by manual steps and inevitable human error.
- Automated deployment ensures much faster delivery.
- Test automation gives you assurance around quality.
- CI/CD done right ensures an end to crippling instability and constant firefighting.
Infrastructure-as-Code
The concept of DevOps means breaking down the barriers between development and operations, deployment and operations. It allows the full team to take ownership of a feature from concept to running in production. You move faster by removing the communication bottlenecks. DevOps done right means using Infrastructure as Code. What does that look like for you?
- All of your cloud infrastructure is written in code instead of using individual, manual steps. All parts of your system, not just the software, are deployed using an automated process.
- You have full visibility on every single change to your entire system.
- When required, you can rebuild your entire system with the press of a button.
- You get a system that is predictable, repeatable and testable.
Observability
We are not just about getting your system into production fast. Observability is about everything that happens afterwards. After all, that’s the most important part, when you are delivering value to your end users. Observability is the practice of ensuring you build software in a way that gives you full insight into what is happening when it runs.
- You want to detect issues before your users do.
- Insights from your production system allow you to constantly improve production quality and performance
- The right metrics are easily available, giving you a deep understanding of what your users are experiencing
