A10 Networks Enables Application Workloads in Oracle Cloud

Guest Author

An application delivery controller (ADC) is in the critical path between the user and an application. A purpose-built ADC provides capabilities like high availability, acceleration, and security for the applications that it front-ends. Applications deployed on-premises require special user and traffic management, monitoring, and logging capabilities that are addressed with a purpose-built ADC.

The A10 vThunder® solution is a purpose-built ADC and is now available in the Oracle Cloud Marketplace. It enables enterprises to carry their secure application delivery policies and practices to Oracle Cloud. Access to real-time visibility into the application traffic is fundamental information for businesses in the multicloud world. The A10 Harmony Controller® is a deep analytics and management platform and provides real-time visibility into application traffic at a per-application, per-flow level.

The following key features are enabled by the A10 vThunder ADC on Oracle Cloud.

Full-Featured Layer 4 and Layer 7 ADC

vThunder provides advanced load balancing for Layer 4 (TCP/UDP) and Layer 7 (HTTP/HTTPS) applications. It has granular, predefined health checks for popular applications such as databases, mail, and http/https, and custom health checks for any application. It can terminate TLS/SSL connections, and inspect and rewrite headers based on user-defined policies. It also provides faster caching functionality and conditional source NAT for improved user experience and optimal use of infrastructure resources. Anything specific that is handled by an enterprise’s on-premises ADC is also available with the vThunder ADC on Oracle Cloud.

Per-App Visibility Across Hybrid Clouds  

The A10 Harmony Controller dashboard enables real-time visibility for every deployed application regardless of where the application is deployed or the underlying infrastructure on which it is deployed.

The following examples show a web application from the dashboard.

High-Availability Support Across Oracle Availability Domain and Regions

vThunder ADC provides stateful high availability (HA) of the application and user sessions between different Oracle availability domains. As such, it provides infrastructure fault tolerance for enterprise applications between the availability domains.

Fault tolerance across Oracle regions or between on-premises and Oracle Cloud can be enabled by using global server load balancing (GSLB). GSLB enables use cases like elastic cloud bursting, business continuity/disaster recovery, and traffic optimization by intelligently routing the end user to the nearest application location.

Host Multiple Applications   

vThunder ADC is designed for multitenancy with fine-grained, role-based access control (RBAC), and it allows enterprises to host multiple applications on the same HA pair. This not only provides efficient use of the infrastructure, but also eases the operations and management associated with network and security functions.       

Integrated Application Security Stack 

The integrated security stack with vThunder provides multiple layers of application and networking security.

  • IPSec: A secure point-to-point connectivity between the on-premises location to Oracle Cloud
  • DDoS: To detect and block DDoS attack from bots and malicious sources at the network and application layer
  • WAF: Web application firewall (WAF) to detect and block application attacks like cross-site scripting, command injection, and protection against application vulnerabilities  
  • IAM/AAM: Application access management (AAM) functionality with integration with identify providers to enable single sign-on (SSO) and multifactor authentication for enterprise applications        

vThunder on Oracle Cloud Marketplace is supported in several form factors, and is available with bring-your-own license (BYOL) or pay-as-you-go. Visit the A10 Networks-Oracle Cloud solution in the Marketplace.
