RightScale vs Vault: What are the differences?

Developers describe RightScale as "Manage all of your cloud infrastructure with a single, integrated solution". Automation is the core of RightScale, freeing you to run efficient, scalable, and highly-available applications. Our multi-cloud integration enables you to choose your own clouds, providing freedom to work with any vendor in a rapidly changing market. And rest assured knowing that you have visibility and control over all of your resources in one place. To take advantage of best practices, we encourage you to tap into cloud expertise provided by our service, support, and partner networks when building and managing your infrastructure. On the other hand, Vault is detailed as "Secure, store, and tightly control access to tokens, passwords, certificates, API keys, and other secrets in modern computing". Vault is a tool for securely accessing secrets. A secret is anything that you want to tightly control access to, such as API keys, passwords, certificates, and more. Vault provides a unified interface to any secret, while providing tight access control and recording a detailed audit log.

RightScale belongs to "Cloud Management" category of the tech stack, while Vault can be primarily classified under "Secrets Management".

Some of the features offered by RightScale are:

• Supports: Amazon Web Services (AWS), Datapipe, Google Cloud Platform, HP Cloud, IDCF — Yahoo! Japan, Rackspace, SoftLayer, Windows Azure, CloudStack, OpenStack
• Access, manage, and configure all of your resources — compute, networking, and storage — across all of your clouds.
• See and manipulate all of your cloud servers in one place.

On the other hand, Vault provides the following key features:

• Secure Secret Storage: Arbitrary key/value secrets can be stored in Vault. Vault encrypts these secrets prior to writing them to persistent storage, so gaining access to the raw storage isn't enough to access your secrets. Vault can write to disk, Consul, and more.
• Dynamic Secrets: Vault can generate secrets on-demand for some systems, such as AWS or SQL databases. For example, when an application needs to access an S3 bucket, it asks Vault for credentials, and Vault will generate an AWS keypair with valid permissions on demand. After creating these dynamic secrets, Vault will also automatically revoke them after the lease is up.
• Data Encryption: Vault can encrypt and decrypt data without storing it. This allows security teams to define encryption parameters and developers to store encrypted data in a location such as SQL without having to design their own encryption methods.

Vault is an open source tool with 13.2K GitHub stars and 1.98K GitHub forks. Here's a link to Vault's open source repository on GitHub.
