## What is Vault?
|
||||
|
||||
Vault is a tool for building, changing, and versioning infrastructure
|
||||
safely and efficiently. Vault can manage existing and popular service
|
||||
providers as well as custom in-house solutions.
|
||||
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.
|
||||
|
||||
Configuration files describe to Vault the components needed to
|
||||
run a single application or your entire datacenter.
|
||||
Vault generates an execution plan describing
|
||||
what it will do to reach the desired state, and then executes it to build the
|
||||
described infrastructure. As the configuration changes, Vault is able
|
||||
to determine what changed and create incremental execution plans which
|
||||
can be applied.
|
||||
|
||||
The infrastructure Vault can manage includes
|
||||
low-level components such as
|
||||
compute instances, storage, and networking, as well as high-level
|
||||
components such as DNS entries, SaaS features, etc.
|
||||
A modern system requires access to a multitude of secrets: database
|
||||
credentials, API keys for external services, credentials for
|
||||
service-oriented architecture communication, etc. Understanding who is
|
||||
accessing what secrets is already very difficult and platform-specific.
|
||||
Adding on key rolling, secure storage, and detailed audit logs is almost
|
||||
impossible without a custom solution. This is where Vault steps in.
|
||||
|
||||
Examples work best to showcase Vault. Please see the
|
||||
[use cases](/intro/use-cases.html).
|
||||
|
||||
The key features of Vault are:
|
||||
|
||||
* **Infrastructure as Code**: Infrastructure is described using a high-level
|
||||
configuration syntax. This allows a blueprint of your datacenter to be
|
||||
versioned and treated as you would any other code. Additionally,
|
||||
infrastructure can be shared and re-used.
|
||||
* **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](http://www.consul.io),
|
||||
and more.
|
||||
|
||||
* **Execution Plans**: Vault has a "planning" step where it generates
|
||||
an _execution plan_. The execution plan shows what Vault will do when
|
||||
you call apply. This lets you avoid any surprises when Vault
|
||||
manipulates infrastructure.
|
||||
* **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.
|
||||
|
||||
* **Resource Graph**: Vault builds a graph of all your resources,
|
||||
and parallelizes the creation and modification of any non-dependent
|
||||
resources. Because of this, Vault builds infrastructure as efficiently
|
||||
as possible, and operators get insight into dependencies in their
|
||||
infrastructure.
|
||||
* **Leasing and Renewal**: All secrets in Vault have a _lease_ associated
|
||||
with it. At the end of the lease, Vault will automatically revoke that
|
||||
secret. Clients are able to renew leases via built-in renew APIs.
|
||||
|
||||
* **Change Automation**: Complex changesets can be applied to
|
||||
your infrastructure with minimal human interaction.
|
||||
With the previously mentioned execution
|
||||
plan and resource graph, you know exactly what Vault will change
|
||||
and in what order, avoiding many possible human errors.
|
||||
* **Revocation**: Vault has built-in support for secret revocation. Vault
|
||||
can revoke not only single secrets, but a tree of secrets, for example
|
||||
all secrets read by a specific user, or all secrets of a particular type.
|
||||
Revocation assists in key rolling as well as locking down systems in the
|
||||
case of an intrusion.

# Use Cases
|
||||
|
||||
Before understanding use cases, it's useful to know [what Vault is](/intro/index.html).
|
||||
This page lists some concrete use cases for Vault, but the possible use cases are
|
||||
much broader than what we cover. Due to its extensible nature, providers and provisioners
|
||||
can be added to further extend Vault's ability to manipulate resources.
|
||||
much broader than what we cover.
|
||||
|
||||
#### Heroku App Setup
|
||||
#### General Secret Storage
|
||||
|
||||
Heroku is a popular PaaS for hosting web apps. Developers create an app, and then
|
||||
attach add-ons, such as a database, or email provider. One of the best features is
|
||||
the ability to elastically scale the number of dynos or workers. However, most
|
||||
non-trivial applications quickly need many add-ons and external services.
|
||||
At a bare minimum, Vault can be used for the storage of any secrets. For
|
||||
example, Vault would be a fantastic way to store sensitive environment variables,
|
||||
database credentials, API keys, etc.
|
||||
|
||||
Vault can be used to codify the setup required for a Heroku application, ensuring
|
||||
that all the required add-ons are available, but it can go even further: configuring
|
||||
DNSimple to set a CNAME, or setting up CloudFlare as a CDN for the
|
||||
app. Best of all, Vault can do all of this in under 30 seconds without
|
||||
using a web interface.
|
||||
Compare this with the current way to store these which might be
|
||||
plaintext in files, configuration management, a database, etc. It would be
|
||||
much safer to query these using `vault read` or the API. This protects
|
||||
the plaintext version of these secrets as well as records access in the Vault
|
||||
audit log.
|
||||
|
||||
#### Multi-Tier Applications
|
||||
#### Employee Credential Storage
|
||||
|
||||
A very common pattern is the N-tier architecture. The most common 2-tier architecture is
|
||||
a pool of web servers that use a database tier. Additional tiers get added for API servers,
|
||||
caching servers, routing meshes, etc. This pattern is used because the tiers can be scaled
|
||||
independently and provide a separation of concerns.
|
||||
While this overlaps with "General Secret Storage", Vault is a good mechanism
|
||||
for storing credentials that employees share to access web services. The
|
||||
audit log mechanism lets you know what secrets an employee accessed and
|
||||
when an employee leaves, it is easier to roll keys and understand which keys
|
||||
have and haven't been rolled.
|
||||
|
||||
Vault is an ideal tool for building and managing these infrastructures. Each tier can
|
||||
be described as a collection of resources, and the dependencies between each tier are handled
|
||||
automatically; Vault will ensure the database tier is available before the web servers
|
||||
are started and that the load balancers are aware of the web nodes. Each tier can then be
|
||||
scaled easily using Vault by modifying a single `count` configuration value. Because
|
||||
the creation and provisioning of a resource is codified and automated, elastically scaling
|
||||
with load becomes trivial.
|
||||
#### API Key Generation for Scripts
|
||||
|
||||
#### Self-Service Clusters
|
||||
|
||||
At a certain organizational size, it becomes very challenging for a centralized
|
||||
operations team to manage a large and growing infrastructure. Instead it becomes
|
||||
more attractive to make "self-serve" infrastructure, allowing product teams to
|
||||
manage their own infrastructure using tooling provided by the central operations team.
|
||||
|
||||
Using Vault, the knowledge of how to build and scale a service can be codified
|
||||
in a configuration. Vault configurations can be shared within an organization
|
||||
enabling customer teams to use the configuration as a black box and use Vault as
|
||||
a tool to manage their services.
|
||||
|
||||
#### Software Demos
|
||||
|
||||
Modern software is increasingly networked and distributed. Although tools like
|
||||
[Vagrant](https://www.vagrantup.com/) exist to build virtualized environments
|
||||
for demos, it is still very challenging to demo software on real infrastructure
|
||||
which more closely matches production environments.
|
||||
|
||||
Software writers can provide a Vault configuration to create, provision and
|
||||
bootstrap a demo on cloud providers like AWS. This allows end users to easily demo
|
||||
the software on their own infrastructure, and even enables tweaking parameters like
|
||||
cluster size to more rigorously test tools at any scale.
|
||||
|
||||
#### Disposable Environments
|
||||
|
||||
It is common practice to have both a production and staging or QA environment.
|
||||
These environments are smaller clones of their production counterpart, but are
|
||||
used to test new applications before releasing in production. As the production
|
||||
environment grows larger and more complex, it becomes increasingly onerous to
|
||||
maintain an up-to-date staging environment.
|
||||
|
||||
Using Vault, the production environment can be codified and then shared with
|
||||
staging, QA or dev. These configurations can be used to rapidly spin up new
|
||||
environments to test in, and then be easily disposed of. Vault can help tame
|
||||
the difficulty of maintaining parallel environments, and makes it practical
|
||||
to elastically create and destroy them.
|
||||
|
||||
#### Software Defined Networking
|
||||
|
||||
Software Defined Networking (SDN) is becoming increasingly prevalent in the
|
||||
datacenter, as it provides more control to operators and developers and
|
||||
allows the network to better support the applications running on top. Most SDN
|
||||
implementations have a control layer and infrastructure layer.
|
||||
|
||||
Vault can be used to codify the configuration for software defined networks.
|
||||
This configuration can then be used by Vault to automatically setup and modify
|
||||
settings by interfacing with the control layer. This allows configuration to be
|
||||
versioned and changes to be automated. As an example, [AWS VPC](http://aws.amazon.com/vpc/)
|
||||
is one of the most commonly used SDN implementations, and [can be configured by
|
||||
Vault](/docs/providers/aws/r/vpc.html).
|
||||
|
||||
#### Resource Schedulers
|
||||
|
||||
In large-scale infrastructures, static assignment of applications to machines
|
||||
becomes increasingly challenging. To solve that problem, there are a number
|
||||
of schedulers like Borg, Mesos, YARN, and Kubernetes. These can be used to
|
||||
dynamically schedule Docker containers, Hadoop, Spark, and many other software
|
||||
tools.
|
||||
|
||||
Vault is not limited to physical providers like AWS. Resource schedulers
|
||||
can be treated as a provider, enabling Vault to request resources from them.
|
||||
This allows Vault to be used in layers: to setup the physical infrastructure
|
||||
running the schedulers as well as provisioning onto the scheduled grid.
|
||||
|
||||
#### Multi-Cloud Deployment
|
||||
|
||||
It's often attractive to spread infrastructure across multiple clouds to increase
|
||||
fault-tolerance. By using only a single region or cloud provider, fault tolerance
|
||||
is limited by the availability of that provider. Having a multi-cloud deployment
|
||||
allows for more graceful recovery of the loss of a region or entire provider.
|
||||
|
||||
Realizing multi-cloud deployments can be very challenging as many existing tools
|
||||
for infrastructure management are cloud-specific. Vault is cloud-agnostic
|
||||
and allows a single configuration to be used to manage multiple providers, and
|
||||
to even handle cross-cloud dependencies. This simplifies management and orchestration,
|
||||
helping operators build large-scale multi-cloud infrastructures.
|
||||
The "dynamic secrets" feature of Vault is ideal for scripts: an AWS
|
||||
access key can be generated for the duration of a script, then revoked.
|
||||
The keypair will not exist before or after the script runs, and the
|
||||
creation of the keys are completely logged.
|
||||
|
||||
This is an improvement over using something like Amazon IAM but still
|
||||
effectively hardcoding limited-access access tokens in various places.
