Virtual machines and volumes

Scalable and HA computing resources for various business tasks

Key features

Three availability zones

Each availability zone is completely independent and has its own infrastructure to deploy cloud resources. The distribution of cloud resources across the three availability zones streamlines fault-tolerant implementations.

High-performance VMs

VM instances run at CPU maximum frequency. For any particular task, you can select the instance type with desired features and change it if necessary. Documentation

Fast and high-capacity volumes

Fast SSD-based volumes support up to 50,000 IOPS to run resource-intensive apps, while cost-efficient HDD-based volumes are good to store large amounts of data in the cloud. You can expand volume capacity (as well as performance, in case of SSD) in real time. Documentation

VM and volume snapshots on the fly

Take snapshots of volumes and entire virtual machines as they run. Ready-to-use volume images and VM templates are stored in a separate storage, making the backup process more reliable. Documentation

Real-time monitoring

The monitoring service allows you to control instance and volume parameters in real time and set automatic threshold-based alerts. Documentation

Flexible management

Manage VMs in the cloud via web interface, AWS-compatible API and CLI, as well as Terraform, Ansible, Packer and many more. Documentation

Resource tagging

Use tags to identify and classify resources of the same type in order to simplify their management. Documentation

Use cases

Typical tasks

General Purpose instances ensure the balance between computing capacity and memory and suit numerous tasks, from running typical apps and small databases to development environments and microservices.

Corporate databases

HPC Optimized instances provide extreme performance for compute-intensive workloads such as 1C enterprise databases.

Distributed computing

Compute Optimized instances are good when you need multiple computing cores but not large RAM, like in CPU-intensive distributed and cluster computing.

In-memory analytics

Memory Optimized instances provide more memory per core than instances of other types and are designed for apps where large data volumes are to be stored in RAM for quicker access (e.g. in-memory analytics).

Scalable volumes for various tasks

CROC Cloud supports several types of virtual volumes that differ in parameters, features, and cost. A volume can be scaled without stopping the attached instance. In addition, volumes can be detached from VMs (except for bootable ones) on the fly and attached to other VMs. All volumes are connected via the VirtIO protocol to increase the efficiency of I/O operations in a virtual environment.

FAQ

What hypervisor is used in CROC Cloud?

CROC Cloud employs a KVM hypervisor.

What about billing?

We use per-hour billing for virtual machines and volumes. VM cost depends on the selected configuration (including the licensed software in use), but not on current load. When a VM is off, payment is taken only for the capacity of attached volumes (high-performance io2 volumes are additionally charged depending on their performance).

What volumes are used in the cloud?

CROC Cloud supports various types of virtual HDD and SSD-based volumes that differ in parameters, features, and cost:st2: Standard (HDD), gp2: Universal (SSD) and io2: Ultimate (SSD). Max capacity and performance per volume are 4 TiB and 50,000 IOPS (for io2) respectively.

You can store large amounts of data in cost-efficient standard HDD-based volumes. Universal enterprise-level SSD-based volumes will suit a wide range of tasks. Ultimate SSD-based volumes are made to run the most demanding applications such as databases with numerous I/O operations. For details, see documentation.

What is CCU and what is it used for?

CCU stands for CROC Compute Unit, which is a unit of measurement for vCPU performance in CROC Cloud and a big help when comparing the performance of different instance types. To count CCUs of a physical core, we run performance tests on a machine under examination and calculate its CCU considering the test results and reference values.
