GCP instances run on top of physical hosts machines managed by Google using virtualization technology. When you spin up a GCP instance, you aren’t necessarily taking an entire host to yourself. Instead, you are sharing the host, with multiple other instances, otherwise known as virtual machines.
What is an instance in cloud computing?
A cloud instance abstracts physical computing infrastructure using virtual machine technology. It is similar to having your own server machine in the cloud. You basically create and manage your own virtual server instance in the cloud computing environment.
What is an instance group GCP?
An instance group is a collection of virtual machine (VM) instances that you can manage as a single entity. Compute Engine offers two kinds of VM instance groups, managed and unmanaged: Managed instance groups (MIGs) let you operate apps on multiple identical VMs.

What is VM instance?
A VM is a virtualized instance of a computer that can perform almost all of the same functions as a computer, including running applications and operating systems. Virtual machines run on a physical machine and access computing resources from software called a hypervisor.
How do I create multiple instances in GCP?
1 AnswerStep 1: "CREATE SNAPSHOT" of the disk. ... Step 2: "CREATE AN IMAGE" with the Snapshot as follows:Step 3: "CREATE AN INSTANCE GROUP TEMPLATE". ... Step 4: "CREATE INSTANCE GROUP" with the newly created instance template; define your desired number of instances to create the instance number.

Connect through a browser from the GCP Marketplace Browse to the Google Cloud Platform console and sign in if required using your Google account. Find and select your project in the project list. Select the “Compute -> Compute Engine” menu item. Locate your server instance and select the SSH button.
How do I access my Google Cloud instance?
Connect to VMsIn the Google Cloud console, go to the VM instances page. Go to VM instances.In the list of virtual machine instances, click SSH in the row of the instance that you want to connect to.
How do I clone a VM in GCP instance?
Your answerGo to the VM instances page.Click the name of the instance you want to clone. The VM instance details page opens.In the toolbar at the top of the VM instance details page, click Create similar. ... In the Create an instance page, customize your new instance.When you have finished, click Create.
Is EC2 the same as a VM?
Amazon Elastic Compute Cloud (EC2) is the Amazon Web Service you use to create and run virtual machines in the cloud (we call these virtual machines 'instances').
What is the difference between an AWS instance and a VM?
A virtual machine is a fully contained object using emulated hardware to provide services. An "instance" is a differential copy of a virtual machine. The source virtual machine for any "instance" is the image from which it is deployed.
What is difference between GCP and AWS?
Google Cloud Platform provides IaaS, PaaS, and serverless computing environments. A comparatively new Google Cloud Platform has all the tools and services required by developers and professionals. Amazon Web Services(AWS): It provides on-demand cloud computing platforms and APIs.
What is the difference between managed and unmanaged instance groups GCP?
The important thing in the unmanaged instance group is you do not get any of the features like auto-scaling or auto-healing. Only the managed instance groups that basically have identical VMs which are created using an instance template have the features of auto-scaling and auto-healing.
How do I add an instance to a GCP instance group?
To do so, go to the Instance groups page in Google Cloud Console, and click on your unmanged instance group's name. This will open the instance group details page. Click on EDIT GROUP . In the VM Instances choose the VM instance that is not already in the group and add it to the group.
What is instance group in AWS?
--instance-groups (list) Specifies the number and type of Amazon EC2 instances to create for each node type in a cluster, using uniform instance groups. You can specify either --instance-groups or --instance-fleets but not both.
What is stateful and stateless in GCP?
The key difference between stateful and stateless workloads is that stateful workloads preserve individual VM state (for example, a database shard, or app configuration) on the VM's disks, while stateless workloads, like a web frontend, do not retain any state on the individual VMs.
Managed Instance group (MIG)
These are identical virtual machine created using instance template. So these VMs, which are part of managed group will have same machine type, same image and the same configuration.
Advantages of using Managed Instance groups
High Availability – High availability consists of Regional coverage, Auto healing, and load balancing to distribute the traffic.
Unmanaged Instance groups
In these unmanaged instance groups, you can have VMs with different configurations, different images, or VMs with different hardware. So if you want to group VMs with different kinds of configurations then you can create an unmanaged instance group.
Auto Healing
Auto healing proactively identifies and replace the unhealthy instances, the ones that are not responding with the healthy one. For Autohealing you need to create a health check, which not only detects whether the machine is running or not but also detects application-specific issues such as freezing, crashing, and overloading.
Load Balancing
It is a fully distributed, software-defined solution that balances user traffic to multiple backends to avoid congestion and ensure low latency. There are different types of Load balancing depending on the type of traffic. They are
Location
The location of the instance group can be either zonal or Regional. You can create it in specific zone or you can specify the instance group to distribute the instances across different zones in a specific region.
What is an instance group?
An instance group is a collection of virtual machine (VM) instances that you can manage as a single entity.
Is there a charge for using managed instances?
There is no additional charge for using managed or unmanaged instance groups. You are charged based on the resources that your group uses. For Compute Engine pricing information, see Pricing.
Overview
The Google Cloud Platform (GCP) is where all of Google Cloud services are located and available via their console page. You will be accessing the Compute Engine service on GCP to create a virtual machine (VM) instance. You can access the SRA data for free in any US region and any zone within the US region.
Launch a GCP Instance
Click the Create Instance button on the top header which will take you to the instance configuration page.
The SRA Toolkit on the GCP
Once you connected, you will be able to work in Unix-like command line environment where you can install and configure the SRA Toolkit.
Engage
NCBI wants your feedback on SRA in the Cloud. Contact [email protected] with questions or if you would like to provide input on new functionality.
What is instance ID?
Instance ID provides a simple API to generate security tokens that authorize third parties to access your app's server side managed resources. Use these tokens now to authorize push messages for your apps via Google Cloud Messaging.
Why delete an instance ID?
For privacy, your app can delete an Instance ID so it is no longer associated with any history in the database. The next time your app calls Instance ID it will get an entirely new Instance ID with no relationship to its previous one.
Can you request a fresh instance ID?
Your app can request a fresh InstanceID whenever needed using the getID () method. Your app can store it on your server if you have one that supports your app.
Why choose GCP?
GCP allows you to choose between computing, storage, big data, machine learning, and application services for your web, mobile, analytics, and, back-end solutions.
What is zone in GCP?
Zones are grouped into regions which are independent geographic areas and much larger than zones (for example- all zones shown above are grouped into a single region Europe-west2) and you can choose what regions you want your GCP resources to be placed in. All the zones within a neighborhood have fast network connectivity among them. Locations within regions usually have trip network latencies of under five milliseconds.
How many regions does GCP have?
Previously, GCP had 15 regions. Visit cloud.google.com to ascertain what the entire is up to today.
