![]() You can launch compute instances with shapes that meet your resource requirements (CPU, memory, network bandwidth, and storage). This architecture includes a load balancer.Ĭompute service enables you provision and manage compute hosts in the cloud. Infrastructure Load Balancing service provides automated traffic distribution from a single entry point to multiple servers in the back end. This architecture uses a single VCN with a private regional subnet. You can change the size of a subnet after creation. ![]() Each subnet consists of a contiguous range of addresses that don't overlap with the other subnets in the VCN. You can segment a VCN into subnets, which can be scoped to a region or to an availability domain. A VCN can have multiple non-overlapping CIDR blocks that you can change after you create the VCN. Like traditional data center networks, VCNs give you complete control over your network environment. Virtual cloud network (VCN) and subnetsĪ VCN is a customizable, software-defined network that you set up in an Oracle Cloud.The load balancer and compute instances in this architecture are deployed in a single availability domain. So, a failure at one availability domain is unlikely to affect the other availability domains in the region. Availability domains don’t share infrastructure such as power or cooling, or the internal availability domain network. The physical resources in each availability domain are isolated from the resources in the other availability domains, which provides fault tolerance. ![]() Regions are independent of other regions, and vast distances can separate them (across countries or even continents).Īll the resources in this architecture are deployed in a single region.Īvailability domains are standalone, independent data centers within a region. Infrastructure region is a localized geographic area that contains one or more data centers, called availability domains. The architecture has the following components: The following diagram illustrates this reference architecture.ĭescription of the illustration siem-logging-oci.png As a Splunk Enterprise administrator, you can collect the streamed data for further analysis by using the Logging Addon for Splunk. Service connectors are used to connect each log to a stream. In this architecture, the Logging service captures load balancer and virtual cloud network (VCN) flow logs. ![]()
