Objective
This guide explains how to use Isolated Containers on Ruk-Com Cloud PaaS, with ordered procedures and practical verification points.
Before you begin
- Sign in with an account permitted to manage the relevant environment.
- Confirm the target environment, region and resources before saving changes.
- Create a backup or rollback plan before changing a production system.
All Ruk-Com Cloud instances such as databases, application servers are containerized and located on different hosts.
Ruk-Com Cloud provides server services according to individual needs, divided into 3 types:
Live migration separation
Live Migration is the process of moving virtual machines without shutting them down. There are some cases where your application requires more and more resources. The server running the node may not have as many resources as you need. Ruk-Com Cloud can complete a live migration of a node to another host in 30 seconds.
During node migration, the application will continue to function properly.vertical scalingAs the application scales within the server Other applications can be migrated to another server to make room. A live migration can send all required resources to another host. The application will not crash and there is no need to restart the container. Moreover, during maintenance the application will remain usable. Or you can perform a downtime to automatically migrate containers from the server.
You can also add instances to an environment usinghorizontal scalingYou don't have to worry about whether there is enough space on the host or not, because Ruk-Com Cloud selects hosts with the right space for moving servers to provide high performance and quality to each of your nodes.
High Availability Isolation for Applications
High Availability (HA) is a nearly always-on system in which the Ruk-Com Cloud platform provides maximum availability by equally distributing containers from one environment to different servers (Hardware nodes) with the help of clusters. anti-affinity to specify that certain containers should not run on the same server
As a result, the Ruk-Com Cloud platform eliminates the risk of application downtime. If one server has performance problems
Security Isolation
Ruk-Com Cloud uses virtualization methods. to run multiple containers simultaneously within a single host These containers are completely separated. without the risk of interfering with each other If the security of another node's container is compromised Other containers are not affected.
Note:This is because each instance within Ruk-Com Cloud PaaS represents a separate containerized service. This will not allow access to other nodes with localhost: port_number or 127.0.0.1:port_number. You should use the same hostname as the container or use private/.publicIP instead and IP may be required to connect the application to the database.
