What's New in the Apcera Platform
This section summarizes what is new in Apcera Platform releases, including long-term support (LTS) and maintenance releases (MR). Refer to the release notes for details on each release. To read about new features in prior releases, see the documentation for the Apcera Platform 2.6 and 2.4 releases.
Apcera Platform release 3.0.0 is an LTS release with the following features and enhancements:
- HA Component Store
- Secure Secret Store
- Cert and Key Management
- Route Management
- Encryption at Rest
- Job Autoscaling
- Configurable Virtual Networks
- Storage Improvements
HA Component Store
The component store is used by the Job Manager, Package Manager, and Auth (Policy) Server to store job metadata. Previously the component store was a PostgreSQL database with cold-backup. In release 3.0 the component store is a key-value store (Consul) that runs on the central host across an odd number of nodes (3, 5, etc.).
See Managing the Component Store for details.
All central components are now HA.
Secure Secret Store
The secret store increases the security of the platform by encrypting and managing application secrets, including certficates, private keys, and passwords. The secret store also secures keys used by cluster components, and stores some cluster secrets such as third-party identity provider credentials.
The secret store runs on the central host and is backed Consul for HA. In support of the secret store, Orchestrator version 2.0 requires a cluster passphrase to deploy and manage a cluster.
See Securing Cluster Secrets for more information.
Cert and Key Management
New certification managment features let you install and manage SSL/TLS certificates and private keys for use with routes, giving you the ability to:
- Upload certificates and keys to the cluster and manage them
- Store secrets securely in the secret store
- Apply certificates and keys to routes for secure custom endpoints
Routes are now first-class job objects in the platform. Previously routes were job properties. You can now perform policy-controlled CRUD operations on routes.
In addition, sticky sessions can now be configured using APC instead of cluster.conf, and support is expanded to include all apps, not just Java.
See Working with Routes for details.
Encryption at Rest
You can now encrypt job application data that is local to the container (ephemeral) or persisted remotely (NFS or SMB). Encryption at rest uses standards-based encryption, LUKS (whole disk encryption) and EncFS (file-level encryption), respectively. Enablement is controlled by policy.
See the following documentation for details:
The Apcera REST API is versioned for all endpoints, and the version is incremented to v2. In addition, both versions of the API are captured in an OpenAPI (Swagger) specification that is available for download, and from which the API endpoint reference documentation is generated.
The endpoint version is implemented as an HTTP header parameter; it is no longer part of the URL. Existing /v1 endpoints will continue to work as is, but you are encouraged to update them to conform with the header method.
Job autoscaling lets you automatically scale job instances up or down based on CPU, request load, requent latency, and custom metrics. The web console provides a complete interface for setting autoscale parameters.
See Auto-scaling Job Instances for details.
Configurable Virtual Networks
With configurable virtual networks you can define custom networks and dramatically scale the number of networks in your cluster. New virtual networks provide subnet pools that run on isolated Layer 2 ethernets, and allow for configurable use of the IP address space, improving isolation and performance.
See Using Configurable Networks for details.
The versions of software used for HA NFS - APCFS (Gluster and Ganesha) are updated to more current versions with upgrade support. In addition, RIAK is replaced as the package store with native Gluster. If you are running RIAK you are encouraged to migrate to Gluster after upgrade.
See Migrating from Riak to Gluster for details.
Stock OS Support for Ubuntu
You can install the Apcera Platform on Ubuntu 14.04.5 (Trusty) using the stock OS. This eliminates thedependency on importing OS images and providing a unified approach to environments, including bare-metal.
See Installing Apcera Platform for your provider.
