Go beyond basic load balancing and unlock a range of business value with advanced solutions. Discover improved visibility, security, automation, and more to support your multi-cloud infrastructure.
Load balancing isn’t just about managing traffic any more. As infrastructure expands to include public, private, and hybrid cloud applications, traffic management has evolved from a technology function to a business function that delivers value to the business. It has also become complex.
The average enterprise runs applications in at least five clouds with over 900+ applications. And most clouds have their load balancers. Microsoft Azure, Amazon Web Services (AWS), and Oracle Cloud Infrastructure have native load balancing that provides basic traffic management, and such solutions are good for simple applications deployed in one location or domain.
But as multi-cloud environments become increasingly complex, how do organisations ensure effective load balancing for their application services deployed in the clouds?
Here are five ways to help unravel cloud complexity
Visibility and Analytics
Performance and reliability of applications are critical to the business. Advanced load-balancing solutions keep apps running with efficiency and reliability in several ways. They use machine learning to set baselines for application performance, user behaviour, etc.
So, organisations can see which assets are doing well and which may be due for an overhaul or have reached the end of life. When a problem is discovered, contextual information helps the operations team troubleshoot faster and more efficiently so optimal customer experience can continue with little interruption. Anomaly detection can be used to drive proactive and even predictive responses.
Businesses undertaking digital transformation can use advanced load balancing to inform decision-making and prioritise their development and infrastructure investments. Visibility, analytics, and insights take the guesswork out of app strategy.
Integrated Security
The scale and scope of attacks are increasing. In public clouds, security is a shared responsibility. The public cloud provider is responsible for securing their infrastructure and data inside their cloud. organisations are responsible for the security of their applications. Understanding these boundaries and implementing full-stack security at both the infrastructure and application levels is important.
The load balancer plays a key role in security because it sits in the best place to reveal patterns around the behaviour of clients. The operations teams can use those patterns to differentiate between legitimate and malicious traffic.
Security that is integrated into the load-balancing solution provides the best defense. organisations will implement security on the load balancer unless the operations team includes security experts. Configuration and management of security features and the ability to adjust policies at a granular level must be straightforward.
Intelligent Automation
New brands and technologies are emerging at a pace faster than ever before, and it is essential that application delivery, security, and load-balancing solutions can integrate with everything.
Many organisations have already implemented continuous integration & continuous deployment (CI/CD) to merge the work of individual developers. Reducing the problems in the release process, CI/CD automatically triggers a build every time a major change is made to the code. Load balancing that is automated and API-driven will integrate with DevOps toolchains, regardless of whether they’re using Ansible, Azure-specific tools, or other technologies.
The need for automation and integration extends beyond the DevOps team. Does an organisation’s load balancer integrate with all the clouds in their infrastructure? An advanced load-balancing solution with strong integration capabilities allows businesses to respond to changes without purchasing new assets and re-set the ROI clock. New products and services can go to market faster when integration makes the infrastructure easy to modify.
Centralised Management
Today, the typical organisation has technology everywhere, and managing traffic can be challenging. An advanced load-balancing solution that provides centralised management will prevent conflicting policies. It will also ensure visibility of the application stack in both public and private clouds and enable multiple regions to accommodate high availability, regulatory requirements, or other needs.
The operations teams can use a central management console to easily create clusters, build elasticity, and scale up or down based on application needs without configuring each application individually. This applies whether the infrastructure runs on a multi-cloud, multi-region environment, or just one cloud. By having a single source of truth through a centralised console, the operations team can drive efficiency by understanding application performance better, detecting anomalies more accurately, and troubleshooting issues faster.

Integration with Containers
Applications have expanded from traditional hardware servers to virtual machines and multiple public and private clouds. With the application infrastructure becoming more and more complex, the adoption of containers is critical. It orchestrates computing, networking, and storage infrastructure for user workloads. This lets organisations deploy cloud-native applications anywhere and control them with confidence.
Kubernetes is the de-facto standard for container orchestration and management. It has been adopted by all the major players, including Microsoft, Amazon, VMware, Red Hat, and its developer, Google. The use of Kubernetes has had a tenfold uptick in adoption in public clouds, and the size of deployments is also increasing.
Any advanced load-balancing technology that integrates with containers not only has to be able to automatically scale to accommodate changes in application traffic but also must automatically update itself when changes are made to the infrastructure. Operations teams won’t have to configure policies or actively manage the load after configuring the advanced load-balancing solution. The operations team can function more efficiently, and an organisation will benefit from them.
In conclusion, today, business and infrastructure are synonymous. Operations teams are pressured to deliver a flexible and secure infrastructure supporting evolving corporate strategies. Advanced load balancers reside in the ideal traffic flow position to help the operations team become more agile and efficient in a multi-cloud environment. But the benefits of advancing load balancing don’t just help operations teams: a company’s decision-makers, security teams, and DevOps departments will also feel the benefits.
