+Resource Types and Dashboard Mapping
|
|
|
|
|
+====================================
|
|
|
|
|
+
|
|
|
|
|
+Cross-Platform Concepts
|
|
|
|
|
+-----------------------
|
|
|
|
|
+
|
|
|
|
|
+Given CloudBridge's goal to work uniformly across cloud providers, some
|
|
|
|
|
+compromises were necessary in order to bridge the many differences between
|
|
|
|
|
+providers' resources and features. Notably, in order to create a robust and
|
|
|
|
|
+conceptually consistent cross-cloud library, resources were given three main
|
|
|
|
|
+properties: ID, name, and label.
|
|
|
|
|
+The `ID` corresponds to a unique identifier that can be reliably used to
|
|
|
|
|
+reference a resource. Users can safely use an ID knowing that it will always
|
|
|
|
|
+point to the same resource.
|
|
|
|
|
+The `name` property corresponds to an unchangeable and unique designation for
|
|
|
|
|
+a particular resource. This property is meant to be, in some ways, a more
|
|
|
|
|
+human-readable identifier. However, when no conceptually comparable property
|
|
|
|
|
+exists for a given resource in a particular provider, the ID is returned
|
|
|
|
|
+instead, as is the case for OpenStack resources. When the name can be
|
|
|
|
|
+determined by a user at resource creation, either the name parameter will be
|
|
|
|
|
+used for resources that support it, or the label will be used, when provided
|
|
|
|
|
+as a prefix, with an appended uuid to ensure that the name remains unique.
|
|
|
|
|
+The `label` property, conversely, is a changeable value that does not need
|
|
|
|
|
+to be unique. Unlike the name property, it is not used to identify a
|
|
|
|
|
+particular resource, but rather label a resource for easier distinction. It
|
|
|
|
|
+is however important to note that not all resources support labels. When
|
|
|
|
|
+supported, labels given at creation will also be used as a prefix to the name.
|
|
|
|
|

|
|
|
|
|
+Properties per Resource per Provider
|
|
|
|
|
+------------------------------------
|
|
|
|
|
+The sections below will present a summary table detailing the CloudBridge
|
|
|
|
|
+properties implemented for each resource, and their corresponding value in
|
|
|
|
|
+the provider's dashboard. It will also delineate the different types of
|
|
|
|
|
+CloudBridge resources, as well as present some design decisions made to
|
|
|
|
|
+preserve consistency across providers.

|
+The resources listed above are labeled. They thus have both the `name` and
|
|
|
|
|
+`label` properties in CloudBridge. These resources require a mandatory `label`
|
|
|
|
|
+parameter at creation. The `label` will then be used to create the `name`,
|
|
|
|
|
+which will consist of up to 55 characters from the label, followed by a UUID.
|
|
|
|
|
+The label property can subsequently be changed, but the name property will
|
|
|
|
|
+remain unchanged, as it is part of the ID. Finally, labeled resources support
|
|
|
|
|
+a `label` parameter for the `find` method in their corresponding services.
|
|
|
|
|
+The below screenshots will help map these properties to Azure objects in the
|
|
|
|
|
+web portal.

|
|
|
|
|
+ The CloudBridge `name` property always maps to the unchangeable resource
|
|
|
|
|
+ name in Azure. The `label` property maps to the tag with key 'Label' for
|
|
|
|
|
+ most resources in Azure. By default, this label will appear in the tags
|
|
|
|
|
+ column, but can also be made into its own column, using the feature
|
|
|
|
|
+ pointed out in the screenshot above.

|
|

|
|
|
|
|
+ which can be found under the properties tab within a resource. The above
|
|
|
|
|
+ screenshot shows where to find a resource's ID in Azure's web portal.

|
|
|
+ The CloudBridge `label` property most often maps to the tag with key
|
|
|
|
|
+ 'Label' in Azure, which can be found under the tags tab within a resource.
|
|
|
|
|
+ The above screenshot shows where to find a resource's label in Azure's
|
|
|
|
|
+ web portal.
|
|
|
|
|
+
|
|
|
|
|
+Two labeled resources are exceptions to the general trends presented above,
|
|
|
|
|
+namely public images (i.e. Azure Marketplace Gallery References) and subnets.
|
|
|
|
|
+
|
|
|
|
|
+Gallery Images are public images from the Azure Marketplace, and cannot be
|
|
|
|
|
+found on a user's dashboard. A Gallery Image Reference is passed by URN, and
|
|
|
|
|
+does not need to be linked to a user. While all Gallery Image References cannot
|
|
|
|
|
+yet be listed in CloudBridge, a pre-set list of popular images is built into
|
|
|
|
|
+CloudBridge. For more on listing images through the Azure CLI, see the
|
|
|
|
|
+`Microsoft Documentation here. <https://docs.microsoft
|
|
|
|
|
+.com/en-us/azure/virtual-machines/linux/
|
|
|
|
|
+cli-ps-findimage#list-popular-images.>`_ Given that these resources are not
|
|
|
|
|
+owned by the user, they can only be referenced by URN. All CloudBridge
|
|
|
|
|
+properties map to the URN and none of them can be set or changed.
|
|
|
|
|
+
|
|
|
|
|
+Additionally, Subnets are a particular resource in Azure because they are
|
|
|
|
|
+not simply found in the Resource Group like most resources, but are rather
|
|
|
|
|
+nested within a network. Moreover, Subnets do not support tags in Azure.
|
|
|
|
|
+However, they remain a labeled resource in CloudBridge, which was
|
|
|
|
|
+accomplished by creating Network tags holding Subnet labels in Azure. The
|
|
|
|
|
+below screenshots will show how to find Subnets and their labels in the
|
|
|
|
|
+Azure web portal.

|

|
|
|
|
|
+ :alt: subnet name in Azure portal
|
|
|
|
|
+
|
|
|
|
|
+ The CloudBridge `name` property for Subnets corresponds to the
|
|
|
|
|
+ unchangeable Resource Name in Azure. However, unlike other resources
|
|
|
|
|
+ where the Azure Name maps directly to the `name` property alone, a Subnet's
|
|
|
|
|
+ `name` property returns the Network's name and the Subnet's name,
|
|
|
|
|
+ separated by a slash, thus having the format [networkName]/[subnetName].
|
|
|
|
|
+ Subnets are additionally not found in the default resource list, but are
|
|
|
|
|
+ rather nested within a Network, in the Subnets tab as shown above.

|

|
|
|
+ :alt: subnet label in Azure portal
|
|
|
|
|
+
|
|
|
|
|
+ The CloudBridge `label` property most often maps to the tag with key
|
|
|
|
|
+ 'Label' in Azure, which can be found under the tags tab within a resource.
|
|
|
|
|
+ However, given that Subnets can't hold tags themselves, we set their tags
|
|
|
|
|
+ in the Network with which they are associated. The tag name 'Label' thus
|
|
|
|
|
+ corresponds to the Network's label, while each contained Subnet will have
|
|
|
|
|
+ a corresponding tag with the name 'SubnetLabel_[subnetName]'.

|
+The resources listed above are unlabeled. They thus only have the `name`
|
|
|
|
|
+property in CloudBridge. These resources require a mandatory `name`
|
|
|
|
|
+parameter at creation, which will directly map to the unchangeable `name`
|
|
|
|
|
+property. Additionally, for these resources, the `ID` property also maps to
|
|
|
|
|
+the `name` in Azure, as these resources don't have an `ID` in the
|
|
|
|
|
+traditional sense and can be located simply by name. Finally, unlabeled
|
|
|
|
|
+resources support a `name` parameter for the `find` method in their
|
|
|
|
|
+corresponding services.

|
|
|
|
+
|
|
|
|
|
+ Bucket and Key Pair objects are different than other resources in Azure,
|
|
|
|
|
+ as they are not resources simply residing in a resource group, but are
|
|
|
|
|
+ rather found in a storage account. As a result of this difference, these
|
|
|
|
|
+ resources do not support labels, and cannot be seen on the default
|
|
|
|
|
+ dashboard. In order to find these resources in the Azure web portal, one
|
|
|
|
|
+ must head to the storage account containing them, and look in the `Blobs`
|
|
|
|
|
+ and `Tables` services respectively for `Buckets` and `KeyPairs`.

|
+Azure - Special Unlabeled Resources
|
|
|
|
|
+-----------------------------------
|
|
|
|
|
++--------------------+------------------------+--------------------+--------------------+----------+
|
|
|
|
|
+| Unlabeled Resource | Azure Resource Type | CB ID | CB Name | CB Label |
|
|
|
|

++--------------------+------------------------+--------------------+--------------------+----------+
|
|

+| FloatingIP | Public IP Address | ID | [public_ip] | - |
|

|
|
++--------------------+------------------------+--------------------+--------------------+----------+
|
|
|
|
|
+
|
|
|
|
|
+While these resources are similarly unlabeled, they do not follow the same
|
|
|
|
|
+general rules as the ones listed above. Firstly, they differ by the fact
|
|
|
|
|
+that they take neither a `name` nor a `label` parameter at creation.
|
|
|
|
|
+Moreover, each of them has other special properties.
|
|
|
|
|
+The FloatingIP resource has a traditional resource ID, but instead of a
|
|
|
|
|
+traditional name, its `name` property maps to its Public IP. Thus, the name
|
|
|
|
|
+seen in the Azure web portal will not map to the CloudBridge name, but will
|
|
|
|
|
+rather be auto-generated, while the Azure `IP Address` will map to CloudBridge
|
|
|
|
|
+name. Moreover, the corresponding `find` method for Floating IPs can thus help
|
|
|
|
|
+find a resource by `Public IP Address`, and the get method also accepts a
|
|
|
|
|
+'Public IP' instead of an 'ID'.
|
|
|
|
|
+
|
|
|
|
|
+In terms of the gateway, one of the major discrepancies in Azure is the
|
|
|
|
|
+non-existence of an InternetGateway. In fact, Azure resources are exposed
|
|
|
|
|
+with no need for an Internet gateway. However, in order to keep resources
|
|
|
|
|
+consistent across providers, the CloudBridge Gateway resource exists
|
|
|
|
|
+regardless of provider. For Azure, the gateway object created through
|
|
|
|
|
+CloudBridge will not appear on the dashboard, but will rather be a cached
|
|
|
|
|
+CloudBridge-level wrapper object.

|
|
|
|
|
+Finally, Firewall Rules in Azure differ from traditional unlabeled
|
|
|
|
|
+resources by the fact that they do not take a `name` parameter at creation.
|
|
|
|
|
+These rules can be found within each Firewall (i.e. Security Group) in the
|
|
|
|
|
+Azure web portal, and will have an automatically generated `name` of the form
|
|
|
|
|
+'cb-rule-[int]'.
