A Service Engine Group defines how Service Engines are created, placed, scaled, and managed for Virtual Services. Properties such as high availability mode, Service Engine sizing, placement rules, scale-out behavior, and rebalance behavior are configured at the Service Engine Group level. Avi documentation includes the Auto Rebalance option as part of Service Engine Group behavior, allowing Avi to redistribute Virtual Services across Service Engines when appropriate. SSL Profiles and Analytics Profiles are normally applied to Virtual Services or associated profiles, not configured as core Service Engine Group properties. The Service Engine management network is normally part of the cloud or infrastructure networking setup rather than the SE Group property asked here. Therefore, the Service Engine Group property listed is Auto Rebalance Policy.

The Basic Virtual Service creation wizard is intended for common application deployment and exposes only the most frequently required settings. Broadcom's Avi documentation describes a Virtual Service as the application endpoint with an IP address, service ports, application type, pools, and related configuration. In the Basic wizard, administrators can choose the Application Type, such as HTTP, HTTPS, or other common application categories, while more detailed profile, policy, analytics, and log-throttle configuration is reserved for Advanced Setup or later editing. TCP/UDP profiles, HTTP Request Policies, and significant log throttle settings are advanced configuration items and are not the typical Basic wizard inputs. Therefore, the option available in Basic Virtual Service creation is Application Type.

The Avi architecture separates control-plane and data-plane responsibilities. Service Engines perform data-plane tasks, including traffic processing, inserting persistence cookies, health checking pool members, and handling load-balanced connections. The Avi Controller provides centralized management, analytics, configuration, and operational visibility. Broadcom's Avi documentation explains that when an administrator requests to view Virtual Service or pool logs, the Controller pulls logs from Service Engines, indexes them, and displays the results. This makes log indexing a Controller function. By contrast, inserting cookies and checking backend server health occur in the Service Engine data plane. Active-active packet processing decisions are also handled by Service Engines according to the Virtual Service placement and traffic flow. Therefore, the task performed by the Avi Controller is indexing client logs.

Connection Multiplexing is most valuable when client behavior would otherwise create many short-lived server-side TCP connections. HTTP/1.0 is the best fit for this benefit because HTTP/1.0 commonly opens a separate TCP connection for each request unless keepalive behavior is specifically used. Avi Connection Multiplexing decouples the client-side connection from the server-side connection and allows the Service Engine to reuse server-side TCP connections for multiple HTTP requests. This reduces connection setup and teardown load on backend servers. HTTP/1.1 already introduced persistent connections as a standard behavior, so the relative benefit is smaller than with HTTP/1.0. HTTP/2 has its own multiplexing model at the protocol level. Therefore, Connection Multiplexing is most valuable for HTTP v1.0.

VMware Avi Load Balancer supports HTTP-to-HTTPS redirection in more than one way. The HTTP application profile can perform a general HTTP-to-HTTPS redirect, but an HTTP Policy provides more granular control because policies can match on specific conditions and then apply actions. Avi documentation states that Virtual Service policies are more specific than general-purpose profiles and that policy rules take precedence over profile behavior. This makes HTTP Policy redirection more flexible than using only the HTTP profile, because administrators can build conditional redirect logic based on host, path, headers, or other HTTP match criteria. It is not incompatible with WAF, and it is not described as less efficient than DataScript for this purpose.
