There is no question that multi-cloud application deployments now play a foundational role in everything from internal business needs to digital transformation initiatives — but it’s also essential for IT operators to ensure effective visibility, governance, security, and control across both public and private clouds as multi-cloud deployments mature into standard IT and operational realms.
According to a global survey report for current state and future direction of multi-cloud deployments, conducted by the Business Performance Innovation (BPI) Network, in partner with A10 Networks, most organizations confront major challenges in ensuring security and best practices across the cloud environments in use. They also face challenges in operating multi-cloud infrastructures with limited IP resources and expertise and improving service visibility and operation efficiency in such complex multi-cloud environments where all resources and data are distributed across all clouds.
As companies leverage a multi-cloud strategy to provide better services to their users, they cannot afford to overlook the implications for security. Meanwhile, there are many issues such as creeping complexity, non-existent cross-platform visibility, and different security standards on each vender’s platform. As a result, most companies end up in a more complex multi-cloud setup than they had envisaged.
Polynimbus is defined as the operations of an enterprise across two or more public or private clouds. The Polynimbus Secure Application Services blueprint outlines the new multi-cloud operational reality enabling higher availability, consistent security and manageability, and greater simplicity and agility for
for organizations as they tackle the complexities of the multi-cloud world. Adoption of the blueprint can mitigate multi-cloud risk and operational challenges, improve compliance, accuracy, and meet DevOps and SecOps needs, with reduced stress on IT personnel.
An application delivery controller (ADC) is a networking device front-ending the appliance servers and/or microservices as a proxy, so that it has real-time and fully visibility into application traffic with control. Here describes how an ADC can enable and augment a Polynimbus application services model.
Server load balancing, one of the core capabilities of the ADC, provides not only application traffic load distribution among back-end servers but also efficient higher availability or redundancy in case of any server failure or downtime. With the ADC’s traffic control capability, operators can easily enable a modern service deployment and operation such as CI/CD processes and blue/green deployment that can avoid service interruption during new service introductions and/or system maintenance for new code updates.
Global server load balancing (GSLB) uses DNS proxy technology to effectively control application traffic globally. As the ADC has real-time visibility to the service health and site conditions, a GSLB enabled ADC can intelligently control and distribute the application requests across all available sites/clouds, and automatically failover to another available site in case of any failure. Using geo-location awareness, operators can provide content localization, and also control traffic and data processing for security and regulatory compliance such as GDPR.
It makes perfect sense to turn on security features on an ADC to protect application services. This way, operators can enable service protection seamlessly without requiring any configuration changes on application servers. Security features include web application firewall, application access management and control, DDoS protection and so on.
Additionally, in a microservices architecture, each node becomes a very small footprint focusing on one specific function (e.g., web service with specific data only) and little or no security concept on it. ADCs can be deployed with security features for north-south traffic, and even for east-west traffic to protect against unwanted access or to enable data encryption.
Consolidating security functions into network functions helps simplify network design and operation involving both IT operator and security teams.
In a multi-cloud environment, where all the resources are distributed globally, it would be difficult for operators to gain a good understanding of the entire application service quality and status. It is essential to have consolidated and deeper service visibility and analytics from a business and OPEX planning perspective. Tracking service status and quality by checking latency or response time will greatly help service monitoring, early failure detection and quick troubleshooting in a complex multi-cloud environment.
Powered by A10 Thunder ADC, Polynimbus mindsets and practices will be the most effective way to ensure that multi-cloud compliance, security policies, functionality, and expectations are met, while easing the burden of over worked and stressed IT and security teams.
