Your requirements might differ from the architecture described here. Most computations are pushed to Elasticsearch. Like the master nodes, Kibana has relatively light resource Low latency and high throughput, which provide for high-performance distributed No-oversubscription 25 Gb network infrastructure. Infrastructure offers powerful bare metal instances that are connected in clusters to a Each data node isĬonfigured with a 200 GiB block storage. We recommend memory-optimized Compute instances becauseĮlasticsearch depends on the amount of memory available. Three data nodes are deployed across three fault domains for highĪvailability. (recommended for bigger clusters) are deployed across three fault domains to Master nodes perform cluster management tasks, such as creating Load balancer is in a public subnet with a public IP address. It uses two listeners, one for Kibana and oneįor index data access, using master node back ends and data node back ends. The load balancer balances index operations to the data nodes and So, you can avoid exposing the more sensitive components of the topology without compromising access to them. The topology has a single, known entry point that you can monitor and audit regularly. It enables you to protect sensitive resources by placing them in private networks that can't be accessed directly from outside the cloud. The bastion host is provisioned typically in a demilitarized zone (DMZ). The bastion host is a compute instance that serves as a secure, controlled entry point to the topology from outside the cloud. When you distribute resources across multiple fault domains, your applications can tolerate physical server failure, system maintenance, and power failures inside a fault domain. Each availability domain has three fault domains with independent power and hardware. So, a failure at one availability domain is unlikely to affect the other availability domains in the region.Ī fault domain is a grouping of hardware and infrastructure within an availability domain. 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. This architecture has the following components:Īvailability domains are standalone, independent data centers within a region. This reference architecture shows a clustered deployment ofĭescription of the illustration elk-oci.png
