Single Sign-On (SSO) for Enterprise

We are pleased to announce that Single sign-on (SSO) is now available for all Enterprise customers.

SSO provides more security and ease-of-use for your employees as they no longer need an Ably password and access can be controlled centrally using your organization's IdP (e.g. Okta or Centrify)

How does it work?

Single sign-on (SSO) allows you to sign in to the Ably dashboard using a single credential and sign in flow managed by your organization.

We’ve implemented SSO for the Ably dashboard using SAML. SAML is a protocol most typically used to address web browser SSO use-cases.

Currently we have support for IdP- and SP-initiated flows, including JIT user creation, and strict mode to enforce SSO for your Ably accounts.

How do I try it?

SSO is currently only available for enterprise. Please contact your account manager if you would like it activated. Once activated please follow the setup instructions.

If you're not on an enterprise account but SSO is important to you, please let us know.

How can I provide feedback?

Please visit the Ably portal where you can tell us what you think of SSO, and other features. Alternatively contact us.

Two-factor authentication

Two-factor authentication (2FA) adds an additional layer of security to your account by requiring more than just a password to log in.

Good news: it's now available for you to try as part of our Early Access program 🎉

How does it work?

Once a user has enabled 2FA, when they log in with a password they will also be sent an SMS with a security code that must be input.

Account owners can also force all users who access their account to have 2FA enabled.

📝 Please note: 2FA is only relevant for those using passwords to log in, so excludes Google, Twitter, GitHub and SAML based authentication.

How do I try it?

Navigate to My Settings in your Ably dashboard, click on the Enable two-factor authentication button, and follow the instructions.

Based on feedback we will consider adding additional 2FA functionality, such as TOTP (e.g. Google Authenticator) and push notifications.

How can I provide feedback?

Please visit the Ably portal where you can tell us what you think of this, and other features. Alternatively contact us.

What is the Early Access program?

The Early Access program is about getting new features into our customer's hands as quickly as possible so that we can use their feedback to help build a better product. ⚠️While all our software is thoroughly tested, early access features haven’t yet had a thorough shakedown so there is a greater chance you will discover bugs. The way certain features work may even change before they are released

New feature: Message Delta Compression. Plus Ably Client Library SDK release v1.2

delta-message-compression-blog.png

Message Delta Compression reduces the bandwidth required to transmit realtime messages by sending only the changes from the previous message to subscribers each time there’s an update, instead of the entire message.

Let’s say the first message sent over a channel is 16KiB and the message after that is the same but with an additional 4KiB of new data. With Delta Compression that message will have a payload of only 4KiB instead of 20KiB.

This reduces bandwidth costs, improves latencies for end-users, and simplifies development by taking care of message size optimization.

Message Delta Compression is a stable feature: we expect it to be forwards-compatible with future Ably updates.

Using Message Delta Compression with an Ably Client Library SDK

When we released Channel Rewind we introduced channel parameters, expressed as a query string in the connection request or channel name itself. This was a first step to specifying parameters on a per channel basis.

With Ably’s 1.2 Client Library SDKs, available today, there’s now a proper ChannelOptions interface to express channel parameters, of which there are three:

The libraries available in this 1.2 release are:

A note on ably-js

We're aware of Ably’s JavaScript Client Library SDK footprint and we're actively avoiding bloat. As such we’ve split out the VCDIFF decoder from the core of ably-js. In order to use Delta Compression with ably-js you need to plug in a separate VCDIFF decoder library. This is hosted on Ably’s CDN. We will be modularizing this in the future, but right now this is something you will need to consider.

Message Delta Compression using a non-Ably library

If you need to use a non-Ably library, say to stream over MQTT, and want to use Delta Compression you’ll need to reconstruct the messages yourself using the deltas. Ably provides a VCDIFF decoder library to decode messages yourself for Java, Cocoa, .NET, and JavaScript. The limitations with this is that you must use channel qualifiers. Read the docs for more.
