What is cloud computing?
Cloud computing is a new Information Technology delivery model which
- Allows for dynamic provisioning of virtual resources.
- The provisioning can be controlled programmatically and can therefore lead to ecosystem creation.
- Lends itself to the pay-for-the-resource-used model.
With IBM SmartCloud Enterprise, customers can access a security-rich, enterprise-ready development and testing environment on IBM's cloud computing platform, to help save capital and operating costs as well as reduce test cycle times, complexity, and risks. A production version of the IBM Cloud is now available in the US and Canada. See how you can get started with the IBM Cloud.
What are the statistics shown on dashboard and my account page?
Active instances is the number of virtual server instances currently in use in the cloud. Active users is the number of users currently having active instances on the cloud. Those numbers will go up and down at any time.
What are the specifications of server sizes?
The selected instance resource may be in 32- or 64-bit configurations; the following table are the specification packages.
|VM component||32-bit Bronze||32-bit Silver||32-bit Gold||64-bit Bronze||64-bit Silver||64-bit Gold||64-bit Platinum|
|Virtual CPU at 1.25GHz||1||2||4||2||4||8||16|
|Virtual memory (GB)||2||4||4||4||8||16||16|
|Instance storage (GB)||175||350||350||850||1024||1024||2048|
A virtual CPU is roughly half of a core of a hyper-threaded real CPU; it is estimated to be 1.25GHz when you take contest switching and other overhead into consideration.
When my instance goes away, where does my data go?
There are two types of storage:
- Ephemeral, instance-dependent storage is part of an instance, created when the instances are instantiated. It goes away irreversibly when the instance is deprovisioned.
- Persistent, instance-independent storage can be mounted to and accessed from several instances. Its life cycle is managed by the user and it is independent of any of the instances that the user may own.
Three sizes of persistent storage are available: 256GB, 512GB, and 2TB.
You have the option to store your data using persistent storage so you can access it whenever you want. If the data is not critical, it will go away when you deprovision the instance. Also, if you don't want to use persistent storage, the data will go away when you remove the instance.
How do I connect to my instance?
This generally depends on the image you used to create your instance. Many software images incorporate a Web server and can be accessed and managed via the browser. All instances can be accessed via SSH. For specific instructions, refer to the description area of your software image in the Asset Catalog.
How do I connect to my instance using SSH?
- From the UNIX shell or cygwin:
ssh -i [ssh private key file] -l idcuser [instance ip address]
- Via PuTTY: in the connection screen click on SSH, Auth, and reference the converted private key. Supply
idcuseras the userid when prompted along with your key passphrase.
Where do I get an SSH client?
For Windows users who need to obtain an SSH client, you might start with PuTTY or Cygwin. (Linux® and Mac users likely already have everything they need.)
How do I get an SSH key?
If you don't have a key, you must download your private key before you can access any instances in the cloud. Note that for security reasons, the Web system will not let you download your private key more than once.
If you are using PuTTY, you will need to convert your downloaded key to the PuTTY format using PuTTYgen. Import the original key, supply the key passphrase, and click Save private key.
Can I use my own SSH key?
Yes, if you would like to generate a key for yourself and use it rather than what we generate, you can go to the account page and within the Access zone, click the Add Key button. Name your key and paste your public key in the contents field and click Continue.
You can generate your own key by opening a command console and typing in the command
ssh-keygen -t rsa. Follow the steps shown on your console and provide your answer accordingly (it is strongly suggested that you use a passphrase!).
How do I capture a custom image?
The custom image feature enables you to provision an instance using one of the base images from the cloud software catalog, modify it, and then save your work to be reused later. Simply select your running instance and click the Create Image button. You'll need to name your image and provide description. Please note that image capture may take considerable time. The captured image will be private, meaning that only your account will be able to provision new instances from it.
How do I provision an instance from my custom image?
Click the Add Instance button and select My Images in the upper right corner on the first screen.
Can I add my private image to the public catalog?
No. If you have an idea for a public image, please contact us (see last answer) — we're always open to good ideas!
Can I manage my persistence storage units?
In your control panel tab, click the Storage area. You are able to attach an available storage unit to your new instance only when you provision it. A storage unit can be attached to only one VM at a time.
How do I manage my reserved IP addresses?
By default, the IP address for your new VM instance gets assigned by the cloud. However, if you wish to transfer the same IP address between your VM instances, you may do so via the reserved IP functionality. To create a manage your reserved IPs, select the account tab and select the Your IPs area. You will be able to assign any of your available reserved IP addresses to a new VM instance when you provision it.
How do I manage firewall rules on my instance?
You can change the iptables rules or insert rules pertaining to your virtual machine into the hypervisor firewall rules. (See this blog entry for specific details to doing either.)
Who can I contact regarding IBM SmartCloud Enterprise?
For help with the cloud, start with the support tab.
