Telecom Innovations: Breaking Down the Barriers to DevSecOps

DevOps—the fusion of software development with IT operations—has been a best practice among development and IT teams for quite some time now. More recently, the need to integrate security within the DevOps process has made DevSecOps the new gold standard for software development and operations. While this may seem like great idea on paper, but what happens when the developers, security architects, and network ops teams are not part of the same company? Telecom networks are typically developed by multiple suppliers.
In many cases, telecom software is developed by external vendors in a walled fashion where Communication Service Providers (CSPs) have little visibility into the development process.
The need to adhere to strict telecom standards and models such as Enhanced Telecom Operations Map (eTOM) and European Telecommunications Standards Institute (ETSI) also compounds the complexity of DevSecOps in telecom. The third barrier is managing a single DevSecOps pipeline while juggling multiple generations of network equipment and configurations
Removing barriers with open telecommunications
What happens when there is no unified environment to support DevSecOps processes? You build one. That’s what Dell Technologies did with the recent launch of its Open Telecom Ecosystem Lab (OTEL). With OTEL, telecom operators and software and technology partners can work together using an end-to-end systems approach that spans seamlessly across vendor, lab, staging, and production environments.
OTEL provides everything that CSPs and vendors need to support DevSecOps processes with the new Solutions Integration Platform (SIP) including:
- Continuous integration across environments
- Continuous deployment of all new software releases in a controlled manner
- Continuous testing to ensure that updates/changes are mostly (80+ percent) automated
- A closed-loop system where pipeline decisions are driven by real-time data insights
A holistic approach to integration, deployment, and testing
In the last few years, there has been a big push to incorporate continuous integration/deployment (CI/CD) pipelines in the telecommunications industry. This push has been met with resistance because of the following challenges:
- Walled software development,
- Multi-generation network technology,
- and stringent requirements around performance, reliability, and security.
Telecom operators’ enterprise customers also have limited involvement in software development despite a deep interest in the functionality and outcomes of that software. For the operaters, becoming a part of the software development process can mean getting services to market sooner with a finished product that meets the needs of end users.
One of the primary goals of OTEL is to deliver telecom innovation as a platform, providing three core capabilities:
- Integrated software development: Although telecom software vendors will ultimately define and control this process, OTEL offers them a unified packaging template and test specifications that can be shared easily across CSP and partner ecosystems.
- Lab and staging environment: Once the software is validated and security-hardened, it can be deployed in the OTEL lab and pre-deployment environments to identify and fix potential issues before deployment in the production network.
- Replicated pre/production environment: OTEL can replicate the production environment to ensure seamless integration between all components.
Addressing the telco security challenges
Telecom Networks are critical infrastructure and have a unique requirements on security driven by service needs and SLA’s, strong regulations and geographical laws, and cyber and data privacy . For 5G and cloud solutions, which involve many vendors, it is important to build a zero trust security architecture that can be validated and tested in a automated CI/CD driven approach. It is also important to enable security mechanisms that can automate security tests across each layer of network. These include:
- Telecom network layer security
- Service layer security
- End point security
- Data platforms and close loop automation
Integrating both the functional and non-functional requirements of telecom networks including security, reliability, and performance is the unique challenge Dell is trying to address through its state of art OTEL . By reducing the complexity of telecom software development and ensuring better integration and collaboration, OTEL is giving CSPs and their partners the agility and security they need to deliver the next generation of 5G and edge solutions.
