Google Compute Engine (GCE) is the Infrastructure as a Service (IaaS) component of Google Cloud Platform which is built on the global infrastructure that runs Google's search engine, Gmail, YouTube and other services. Google Compute Engine enables users to launch virtual machines (VMs) on demand. VMs can be launched from the standard images or custom images created by users. GCE users must authenticate based on OAuth 2.0 before launching the VMs. Google Compute Engine can be accessed via the Developer Console, RESTful API or command-line interface (CLI).

|Type||Virtual Private Server|
Google announced Compute Engine on June 28, 2012 at Google I/O 2012 in a limited preview mode. In April 2013, GCE was made available to customers with Gold Support Package. On February 25, 2013, Google announced that RightScale was their first reseller. During Google I/O 2013, many features including sub-hour billing, shared-core instance types, larger persistent disks, enhanced SDN based networking capabilities and ISO/IEC 27001 certification got announced. GCE became available to everyone on May 15, 2013. Layer 3 load balancing came to GCE on August 7, 2013. Finally, on December 2, 2013, Google announced that GCE is generally available. It also expanded the OS support, enabled live migration of VMs, 16-core instances, faster persistent disks and lowered the price of standard instances.
At the Google Cloud Platform Live event on March 25, 2014, Urs Hölzle, Senior VP of technical infrastructure announced sustained usage discounts, support for Microsoft Windows Server 2008 R2, Cloud DNS and Cloud Deployment Manager. On May 28, 2014, Google announced optimizations for LXC containers along with dynamic scheduling of Docker containers across a fleet of VM instances.
Google compute engine unit (GCEU), which is pronounced as GQ, is an abstraction of computing resources. According to Google, 2.75 GCEUs represent the minimum power of one logical core (a hardware hyper-thread) based on the Sandy Bridge platform.
Every Google Compute Engine instance starts with a disk resource called persistent disk. Persistent disk provides the disk space for instances and contains the root filesystem from which the instance boots. Persistent disks can be used as raw block devices. By default, Google Compute Engine uses SCSI for attaching persistent disks. Persistent Disks provide straightforward, consistent and reliable storage at a consistent and reliable price, removing the need for a separate local ephemeral disk. Persistent disks need to be created before launching an instance. Once attached to an instance, they can be formatted with the native filesystem. A single persistent disk can be attached to multiple instances in read-only mode. Each persistent disk can be up to 10TB in size. Google Compute Engine encrypts the persistent disks with AES-128-CB, and this encryption is applied before the data leaves the virtual machine monitor and hits the disk. Encryption is always enabled and is transparent to Google Compute Engine users. The integrity of persistent disks is maintained via a HMAC scheme.
An image is a persistent disk that contains the operating system and root file system that is necessary for starting an instance. An image must be selected while creating an instance or during the creation of a root persistent disk. By default, Google Compute Engine installs the root filesystem defined by the image on a root persistent disk. Google Compute Engine provides CentOS and Debian images as standard Linux images. Red Hat Enterprise Linux (RHEL) and Microsoft Windows Server 2008 R2 images are a part of the premier operating system images which are available for an additional fee. CoreOS, the lightweight Linux OS based on Chromium OS is also supported on Google Compute Engine.
Google Compute Engine uses KVM as the hypervisor, and supports guest images running Linux and Microsoft Windows which are used to launch virtual machines based on the 64 bit x86 architecture. VMs boot from a persistent disk that has a root filesystem. The number of virtual CPUs, amount of memory supported by the VM is dependent on the machine type selected.
Once an instance is run for over 25% of a billing cycle, the price starts to drop:
Google provides certain types of machine:
|Machine type||Machine name||Virtual cores||Memory||Cost per hour (US hosted)||Cost per hour (Europe hosted)|
Compute Engine connects various entities called resources that will be a part of the deployment. Each resource performs a different function. When a virtual machine instance is launched, an instance resource is created that uses other resources, such as disk resources, network resources and image resources. For example, a disk resource functions as data storage for the virtual machine, similar to a physical hard drive, and a network resource helps regulate traffic to and from the instances.
An image resource contains an operating system and root file system necessary for starting the instance. Google maintains and provides images that are ready-to-use or users can customize an image and use that as an image of choice for creating instances. Depending on the needs, users can also apply an image to a persistent disk and use the persistent disk as the root file system.
An instance's machine type determines the number of cores, the memory, and the I/O operations supported by the instance.
Persistent disks are independent of the virtual machines and outlive an instance's lifespan. All information stored on the persistent disks is encrypted before being written to physical media, and the keys are tightly controlled by Google.
|Type||Price (per GB/month)|
|Standard provisioned space||$0.04|
|SSD provisioned space||$0.17|
|IO operations||No additional charge|
Each instance can attach only a limited amount of total persistent disk space (one can have up to 64 TB on most instances) and a limited number of individual persistent disks (one can attach up to 16 independent persistent disks to most instances).
Persistent disk snapshots lets the users copy data from existing persistent disk and apply them to new persistent disks. This is especially useful for creating backups of the persistent disk data in cases of unexpected failures and zone maintenance events.
A Google Compute Engine instance is a virtual machine running on a Linux or Microsoft Windows configuration. Users can choose to modify the instances including customizing the hardware, OS, disk, and other configuration options.
A network defines the address range and gateway address of all instances connected to it. It defines how instances communicate with each other, with other networks, and with the outside world. Each instance belongs to a single network and any communication between instances in different networks must be through a public IP address.
Your Cloud Platform Console project can contain multiple networks, and each network can have multiple instances attached to it. A network allows you to define a gateway IP and the network range for the instances attached to that network. By default, every project is provided with a default network with preset configurations and firewall rules. You can choose to customize the default network by adding or removing rules, or you can create new networks in that project. Generally, most users only need one network, although you can have up to five networks per project by default.
A network belongs to only one project, and each instance can only belong to one network. All Compute Engine networks use the IPv4 protocol. Compute Engine currently does not support IPv6. However, Google is a major advocate of IPv6 and it is an important future direction.
When an instance is created, an ephemeral external IP address is automatically assigned to the instance by default. This address is attached to the instance for the life of the instance and is released once the instance has been terminated. GCE also provides mechanism to reserve and attach static IPs to the VMs. An ephemeral IP address can be promoted to a static IP address.
A firewall resource contains one or more rules that permit connections into instances. Every firewall resource is associated with one and only one network. It is not possible to associate one firewall with multiple networks. No communication is allowed into an instance unless a firewall resource permits the network traffic, even between instances on the same network.
Google Compute Engine offers a routing table to manage how traffic destined for a certain IP range should be routed. Similar to a physical router in the local area network, all outbound traffic is compared to the routes table and forwarded appropriately if the outbound packet matches any rules in the routes table.
A region refers to a geographic location of Google's infrastructure facility. Users can choose to deploy their resources in one of the available regions based on their requirement. As of June 1, 2014, Google Compute Engine is available in central US region, Western Europe and Asia East region.
A zone is an isolated location within a region. Zones have high-bandwidth, low-latency network connections to other zones in the same region. In order to deploy fault-tolerant applications that have high availability, Google recommends deploying applications across multiple zones in a region. This helps protect against unexpected failures of components, up to and including a single zone. As of August 5, 2014, there are eight zones - three each in central US region and Asia East region and two zones in Western Europe region.
All resources within GCE belong to the global, regional, or zonal plane. Global resources are accessible from all the regions and zones. For example, images are a global resource so users can launch a VM in any region based on a global image. But an address is a regional resource that is available only to the instances launched in one of the zones within the same region. Instances are launched in a specific zone that requires the zone specification as a part of all requests made to that instance.
The table below summarises the scope of GCE resources:
Google charges the VMs for a minimum of 10 minutes. At the end of 10th minute, instances are charged in 1-minute increments, rounded up to the nearest minute. Sustained usage based pricing will credit the discounts to the customers based on the monthly utilisation. Users need not pay a commitment fee upfront to get discounts on the regular, on-demand pricing.
Compute Engine VMs boot within 30 seconds which is considered to be 4-10x faster than the competition.
Images and disk snapshots belong to the global scope which means they are implicitly available across all the regions and zones of Google Cloud Platform. This avoids the need for exporting and importing images and snapshots between regions.
During the scheduled maintenance of Google data center, Compute Engine can automatically migrate the VMs from one host to the other without involving any action from the users. This delivers better uptime to applications.

Apache Ignite is an open-source distributed database, caching and processing platform designed to store and compute on large volumes of data across a cluster of nodes.Ignite was open-sourced by GridGain Systems in late 2014 and accepted in the Apache Incubator program that same year. The Ignite project graduated on September 18, 2015.Apache Ignite's database utilizes RAM as the default storage and processing tier, thus, belonging to the class of in-memory computing platforms. The disk tier is optional but, once enabled, will hold the full data set whereas the memory tier will cache full or partial data set depending on its capacity.
Regardless of the API used, data in Ignite is stored in the form of key-value pairs. The database component scales horizontally, distributing key-value pairs across the cluster in such a way that every node owns a portion of the overall data set. Data is rebalanced automatically whenever a node is added to or removed from the cluster.
On top of its distributed foundation, Apache Ignite supports a variety of APIs including JCache-compliant key-value APIs, ANSI-99 SQL with joins, ACID transactions, as well as MapReduce like computations.
Apache Ignite cluster can be deployed on-premise on a commodity hardware, in the cloud (e.g. Microsoft Azure, AWS, Google Compute Engine) or in a containerized and provisioning environments such as Kubernetes, Docker, Apache Mesos, VMWare.AppScale
AppScale is an open-source serverless computing platform that automatically deploys and scales unmodified Google App Engine applications over public and private clouds, as well as on-premises clusters. AppScale is modeled on the App Engine APIs and has support for Go, Java, PHP, and Python applications.The goal of AppScale is to provide developers with a rapid, API-driven development platform that can run applications on any cloud infrastructure. AppScale decouples app logic from its service ecosystem to give developers and cloud administrators control over app deployment, data storage, resource use, backup and migration.The platform allows developers to focus on the business logic of building scalable applications, freeing them from the need to concentrate on deployment and scaling logic. AppScale decouples app logic from its service ecosystem to give developers and cloud administrators control over app deployment, data storage, resource use, backup, and migration.AppScale includes high-level APIs for persistence, asynchronous execution, distributed memory cache, user authentication, and more. It handles service discovery, load-balancing, fault-tolerance, and auto-scaling. It also allows IT operations and cloud administrators to provide a consistent, tunable environment for running and maintaining apps on multiple cloud infrastructures.
AppScale is developed and maintained by AppScale Systems, Inc., based in Santa Barbara, California, and Google.Autoscaling
Autoscaling, also spelled auto scaling or auto-scaling, and sometimes also called automatic scaling, is a method used in cloud computing, whereby the amount of computational resources in a server farm, typically measured in terms of the number of active servers, scales automatically based on the load on the farm. It is closely related to, and builds upon, the idea of load balancing.BOSH (software)
BOSH is an open source project that offers a tool chain for release engineering, deployment & life-cycle management of large scale distributed services. Namely, this tool chain is made of a server (the BOSH Director) and a command line tool. BOSH is typically used to package, deploy and manage cloud software. While BOSH was initially developed by VMware in 2010 to deploy Cloud Foundry PaaS, it can be used to deploy other software (such as Hadoop, RabbitMQ, or MySQL for instance). BOSH is particularly well-suited for managing the whole life cycle of large distributed systems.
Since March 2016, BOSH can manage deployments on both Windows and Linux servers.
A BOSH Director communicates with a single IaaS that provides the underlying networking and VMs (or containers). Several IaaS providers are supported: Amazon Web Services EC2, Apache CloudStack, Google Compute Engine, Microsoft Azure, OpenStack, and VMware vSphere.
To help support more underlying infrastructures, BOSH uses a concept of Cloud Provider Interface (CPI). There is an implementation of the CPI for each of the IaaS listed above. Typically the CPI is used to deploy VMs, but it can be used to deploy containers.
Few CPIs exist for deploying containers with BOSH, and only one actively supported. For this, BOSH uses a CPI that deploys Pivotal's Garden containers (Garden is very similar to Docker) on a single virtual machine, run by VirtualBox or VMware Workstation. In theory, any other container engine could be supported, if the necessary CPIs were developed.
Due to BOSH indifferently supporting deployments on VMs or containers, BOSH uses the generic term “instances” to designate those. It is up to the CPI to choose whether a BOSH “instance” is actually a VM or a container.Cloud database
A cloud database is a database that typically runs on a cloud computing platform, and access to the database is provided as-a-service.
Database services take care of scalability and high availability of the database. Database services make the underlying software-stack transparent to the user.Cloudscaling
The Cloudscaling Group, Inc., was a software company based in San Francisco, California, USA. The company’s Open Cloud System is a cloud computing system based on the OpenStack open-source software project. It is used to deploy infrastructure as a service (IaaS) public, private and hybrid clouds that support applications typically found on public cloud infrastructures such as Amazon Web Services or Google Compute Engine. These applications are often referred to as cloud-ready applications, which Cloudscaling refers to as dynamic applications and are contrasted with traditional enterprise IT applications.Cycle Computing
