Digital business is here to stay
Organizations around the world are accelerating moves to online digital business as a result of pandemic restrictions, global economic disruptions, and ongoing uncertainty. 97% of enterprises expect to use connected hybrid and multi-cloud infrastructure to support cloud-native applications. 99% of organizations are using or are evaluating the use of containers and microservices to enable future application development activities.
Market dynamics are changing as a result of this digital business transformation. Data about every aspect of business activity and interaction can be captured and analyzed. Applications are being created modularly and updated continuously to stay current. Citizens, employees, and partners can collaborate with agencies and businesses on-line and in real time.
More agencies in state, local, and federal government as well as education are building Information Technology (IT) modernization and digital transformation strategies, and adopting cutting edge technologies as well as utilizing existing IT infrastructure to execute those strategies. A prime example of this movement is containerization, which many agencies are beginning to deploy in their environment to replace aging, expensive virtualization infrastructure.
DevSecOps is key when replacing infrastructure
To enable enterprise IT across agencies and organizations, and ensure the right strategy, tools, partners, people and processes are in place, requires an investment in DevSecOps methodologies and practices. Delivering capabilities with microservices architectures are needed to accelerate agile software development and take advantage of automated continuous integration/continuous delivery (CI/CD) toolchains to create and deploy digital business applications faster than ever. Increasingly, these solutions are being designed as cloud-native applications optimized for highly scalable container infrastructure orchestrated using Kubernetes.
Kubernetes, an open source container orchestration technology, has been widely adopted across the industry and is supported by many on-premises distributions and public cloud container services. Kubernetes automatically manages container service discovery, incorporates load balancing, tracks resource allocation, and scales container deployments based on compute utilization.
Based on an organization or agency’s unique priorities, the best mix of infrastructure and application architectures can be built that will optimize agility, control costs, and maintain security. Moreover, 71% of organizations recognize the need for consistent cross-cloud management and automation to ensure effective application performance and business operations . Modern digital business strategies depend on microservices and cloud-native architectures. Large-scale operations across multiple clouds and clusters pose management challenges beyond what Kubernetes can manage on its own.
Containers are important. So, why are organizations struggling to manage them?
Despite the rapid adoption of containers, many organizations are struggling to manage and secure them effectively. Only 15% of organizations surveyed by IDC have developed, optimized or fully mature strategies for managing and taking full advantage of containers across the application life cycle. Organizations are particularly concerned about the impact on cloud cost management, workload placement decisions, adapting to new automation GitOps strategies built for containers, and maintaining security, compliance, and observability strategies, especially as applications become more distributed and global.
The ability to consistently manage distributed applications built and operated on modern frameworks and technologies like containers, across diverse on-premises and public cloud platforms is crucial to digital business success. The ability to deliver these environments and workloads into production as highly available, secure, high performing enterprise IT services to users, customers, and constituents, requires a comprehensive platform with the tools that address the new challenges and dynamics that they present in order to achieve the gains and return on investment that organizations seek to deliver.
Effective container environment management at scale
Because each container can operate in isolation from another, developers can use containers to modularize development using microservices and work on each microservice individually. Rather than being patched and updated while running, containers are simply terminated, and new updated containers are launched as needed to introduce new functions or to repair performance problems. This allows for the rapid scaling and deployment of updates in a consistent manner across a cluster.
Organizations are rapidly adopting technologies like containers and kubernetes to respond more quickly to the wants and needs of their customers and deliver better business outcomes in a controlled and in alignment with enterprise IT governance requirements. These improved business outcomes are coming in the form of cost savings, better agility and self-service for their users which improves process and speed to market, and in some cases, even stronger security and improved posture when it comes to reducing the risk of vendor lock-in.
The benefits of a multi-cluster architecture
Kubernetes is focused on managing individual clusters, however, it is not designed to control multi-cluster operations or security on its own as an upstream project deployed in a DIY manner without additional tooling and technologies. As a result, as use of containerized applications increases, many enterprises are adopting multi-cluster Kubernetes architectures that allow each cluster to be configured to meet specific local configuration, compliance, and performance requirements as needed in different physical locations, geographies, and clouds.
Multi-cluster architectures allow better alignment of security and operational policies with different application and business needs. This is an emerging technology area that specifically enables policy-based operations and consistent control across multiple Kubernetes clusters, whether they are deployed on premises, in public clouds, or at the edge. Effective multi-cluster Kubernetes management is a priority for organizations that are successfully building out cloud-native, agile DevSecOps programs for business transformation.
