For a more in-depth look into Persistent Disk check out the documentation. Use the pointers in this post to help you identify the option that works best for your use case. Whatever your application use case maybe, if you are using a virtual machine or a Google Kubernetes Engine instance then you will be making a block storage choice. But, if your app demands even higher availability and is mission critical then there is an option to use a regional persistent disk, which is replicated across zones for near zero Recovery Point Objective (RPO) and Recovery Time Objective (RTO) values. For most workloads you would be fine with Persistent Disk it is durable and supports automated snapshots. Use Local SSD if you just need ephemeral storage for a stateless app that manages the replication at the application level or database layer. You can also choose a Persistent Disk based on the availability needs of your app. How to pick block storage based on availability needs It is best for hot caches that offer best performance for analytics, media rendering, and other use cases that might require scratch space. Click the PC icon in Cheat Engine in order to select the game process. Local SSD is recommended if your apps need really low latency. These could include SAP HANA, Oracle, and the largest in-memory databases. It is best suited for performance sensitive applications such as databases, caches, and scale out analytics.Įxtreme PD is SSD optimized for applications with uncompromising performance requirements. Now pause the game to access a new Features menu that allows level selection. Performance PD is SSD and provides the best price per IOPS (input/output operations per second). The Persistence Enhanced features adaptive trigger pressure feedback for the various ranged weapons in the game such as the Sentinel, Valkryie, or the Grav Hook for example each requiring different trigger pressure to master your attack. This makes it a good fit for common workloads such as line of business apps, boot disks, and web serving. Because it is the most cost effective option, it is best used for cost-sensitive applications and scale out analytics with Hadoop and Kafka.īalanced PD is SSD and is the best price per GB option. Standard PD is HDD and provides standard throughput. You can choose the best Persistent Disk option for you based on your cost and performance requirements. You can attach multiple persistent disks to Compute Engine or GKE simultaneously and can configure quick, automatic, incremental backups or resize storage on the fly without disrupting your application. In Google Cloud it means they are attached to Compute Engine or Kubernetes Engine. These disks store data in blocks and are attached to compute. Persistent Disk is a high performance block storage service that uses solid state drive (SSD) or hard disk drive (HDD) disks. “Where do virtual machines store data so they can access it when they restart?”-We need storage that is persistent in nature.
