Like any computing, the primary pillars driving Cloud Computing is a combination of CPU, memory, networking, and storage. Most Infrastructure as a Service (IAAS) platforms, like CenturyLink Cloud, provide two storage solutions, Block & Object. Understanding the differences between these two formats is critical when designing an overall IaaS or Storage Solution.
Block Storage Solutions provide fixed-sized raw storage capacity. Each block storage node can be treated as an independent drive & controlled by an external or attached server. Generally, each node can be mounted by the server as if it were a physical dirve. The most common examples of Block Storage are SAN, iSCSI, and local disks. However, IaaS providers highly-available, fault-tolerant & redundant options that are becoming much more popular given their relatively low cost & ability to avoid the capital expenditure associated with acquiring, building & maintaining the infrastructure internally.
With storage options supporting up to 20,000 IOPS, your applications will run at peak speed (using a 4k block size).
Each Cloud Server can be configured with Premium storage, offering 14 days of rolling disaster recovery, or Standard, which provides 5 days.
Create ad-hoc snapshots, templates and archive VMs from within the CenturyLink Cloud Control Portal.
Increase disk space or add additional storage disks to existing servers through the Control Portal. For servers that require more storage over time, adding more space is simple.
CenturyLink’s approach to cloud storage offers more flexibility in a number of dimensions. Decide what type of storage each scenario requires, and then specify the type of automated DR/BC that’s needed to support the use case. You aren't tied into a predefined scheme of “small”, “medium” or “large” instances.
Demanding application components (such as the data store of your database) require high I/O to deliver a compelling user experience. CenturyLink’s product catalog includes these high-end options for exactly this reason.
The storage requirements for any virtual machine are never static. As business needs change, the storage attributes of a deployed VM are likely to change as well. CenturyLink empowers you to do this on your own, as required.
