![]() ![]() These local disks are only available in the hardware where the virtual machine is running and, while providing the best I/O performance, they are not often recommended due to the low availability and redundancy. While local disks are not, in theory, part of the Google Cloud Persistent Disk service, it is important to mention them. In addition, there is also the ability to choose where they are located and what type of availability is needed: they can be Regional, Zonal, or Local. Very much like a virtual disk in your local machine, a Google Cloud Persistent Disk can either be HDD or SSD, the latter for high I/O performance. In addition to Google Cloud Compute Engine virtual machines, these Persistent Disks are also used to power the Google Kubernetes Engine service. They can be attached or detached from virtual machines and enable you to build, as the name suggests, data persistence for your services whenever virtual machines are started, stopped, or terminated. The easiest way to understand it is by imagining those Persistent Disks as mere USB drives. A Google Cloud Persistent Disk provides block storage and it is used by all virtual machines in Google Cloud (Google Cloud Compute Engine). Google Cloud Persistent Disks (Block Storage)īlock storage is the traditional storage type, both in the cloud and in on-premises systems. Let’s take a closer look at each of these Google Cloud storage services, what they were designed for, and what use cases they are each best suited to handle. Since NetApp Cloud Volumes ONTAP is now available in the Google Cloud, NetApp users can easily take advantage of this growing cloud platform. These services are at the core of the platform and act as building blocks for the majority of the Google Cloud services and, by extension, to the systems you build on top of it. Google Cloud provides three main services for different types of storage: Persistent Disks for block storage, Filestore for network file storage, and Cloud Storage for object storage. In this article, we are going to provide some clarity about the different storage options in the Google Cloud Platform. However, if you are used to the world of data centers, like Google Cloud Storage -with SAN, NAS, and local hard drives-and are starting to venture into public cloud, the concept of cloud-based storage and the different services available for it might prove tricky. Regardless if your systems are on-premises, in the cloud, or both, you always rely on storage components to persist your data. Alongside compute and network, storage is one of the fundamental resources required in today’s technological systems and software development. ![]()
