APIs are a fundamental building block of cloud-native and containerized application development. By enabling operational teams to work collectively, APIs can speed up time-to-market for application development and help you deliver better user experiences than your competitors. On the flipside, the use of APIs has decentralized the structure of applications. This makes API design, publishing, and management tougher, which in turn creates a complex and risk-prone management challenge. Without automated and high-performance traffic and policy controls, API growth and complexity will slow down developer agility.
F5 offers a comprehensive solution to safely manage APIs across any data center or cloud using a simple, fast, and scalable architecture. This helps improve time-to-market by enabling automation of API deployments and management, while also protecting against API-specific threats. F5 provides cloud-native API management, high-performance API gateways, and security controls all in one solution, reducing tool sprawl and architectural complexity.

Application development moves swiftly and innovation is continually changing the face of our interactions. Because of distributed container complexities, this emphasis on speed sometimes leads to resistance to API management and enforcement of security and infrastructure controls. Unfortunately, because APIs are increasingly consumed by microservice-to-microservice data exchange, they are becoming a potential vulnerability that could expose sensitive data. This means that all API endpoints should have at least a minimum degree of standardized risk, configuration, and policy enforcement; however, because API publishing automation removes traditional elements of user interaction and oversight, the same trends making APIs more valuable are also making them more vulnerable.
API gateways are typically designed to manage publishing of APIs to a platform or to microservice clusters; ease of use and automation are the primary drivers for adoption because it’s difficult to scale API interconnectivity to meet customer traffic demands as your application portfolio grows while remaining platform agnostic. This explains why API misconfigurations and security lapses have been the cause of some of the highest-profile API data breaches.
DevOps is responsible for increasing numbers of automation pipelines, each requiring different tools to meet developer and application requirements. These scenarios create disconnected API traffic patterns and management instances, further complicated by disconnected observability solutions. Unfortunately, it is still common for development and DevOps teams to be measured on their release frequency—but not their release security.
The result is enterprise API growth management failures at scale, creating new and unintended risk and exposure from unauthorized API usage—some of the most common threats according to OWASP’s API Security Top 10.
APIs also encounter performance issues when managing traffic at scale. A 50–100 millisecond transaction delay could be acceptable for an application’s initial rollout, but when multiplied across hundreds or thousands of microservices scaling to meet customer demand, those delays add up and slow the entire application chain. The result? Poor performance and failed customer expectations.
Automating API endpoint access, configuration, and security across the enterprise application portfolio, from initial development to production deployment, will allow DevOps to address performance and potential vulnerabilities at scale so they can focus on other automation pipeline issues.
Cloud-native applications are increasingly distributed and decentralized by design, relying on hundreds, if not thousands, of API-based endpoints, with millions of transactions as the primary source of traffic. Recent F5 Labs research shows that the number of API security incidents is growing every year and that the most frequent causes of API incidents in the last two years are related to low levels of security maturity, often caused by tool sprawl.
When different development teams work on different parts of distributed applications across multiple platforms, it creates API management complexity that results in insecure and poorly performing applications. Problems can arise from deployment failures, degraded performance, or malicious access to sensitive traffic, and it’s difficult to remediate, much less pinpoint, the cause. Reducing this complexity at scale reduces risk and provides a consistent set of configuration, performance, and security policies optimized around your business goals. Providing DevOps a standard set of tools to automate the right controls into API development and management processes allows your applications to grow alongside your business.
Enterprises need to maintain and evolve their traditional APIs, while simultaneously developing new ones using cloud-native microservice architectures. These can be delivered either with bare metal private systems, from the cloud, or through multi-cloud transit solutions. APIs are difficult to categorize as they are used in delivering a variety of user experiences, each one potentially requiring a different set of development, publishing, and security controls. The flexibility of F5 NGINX solutions can address multiple different use cases or architectural patterns to meet the requirements of any dev team.
In their Cloud Market Trend Report, Futuriom reports “APIs have been a crucial element of data center and SD-WAN virtualization, and they will become increasingly important to connect multi-cloud networks.”
In all of the solutions outlined below, F5 NGINX Management Suite is used for API management functions such as publishing the APIs, setting up authentication and authorization, and using the API gateway offered in F5 NGINX Plus to form the data path. Security controls are addressed based on the security requirements of the data and API delivery platform.
F5’s solutions deliver, manage, and secure APIs and the infrastructure used to host them, regardless of your platform or automation architecture. F5 provides strong protection against bots and common and advanced API exploits, with DevOps integration for publishing and visibility into API performance. Combined, these solutions help you reach your goal of application portability anywhere you deploy, bringing workloads closer to your customers.
Give your dev and ops teams the agility necessary to support the business now by providing them the freedom to use the right environment for the job—whether cloud-hosted or on-premises—and the versatility to support the business in the future, with architecture portability that moves when you move.
