# What is layline.io?

layline.io is an opinionated message processor. It wraps the power of akka-streams in a framework which makes setup, deployment and monitoring of large scale message processing requirements easy and straightforward. layline.io provides everything you would expect from a product-base solution including upgradability, carrier-grade resilience and scalability, among other features.

# Motivation

The world is transitioning from analog to digital at an ever faster pace. These transformation processes need to ever increasing requirements towards data gathering, data analysis, and data exchange. Mainly in real-time. While there are ways to manage, these are - in many ways - exclusive to large corporations with respective IT-muscle and budgets.

The volume of information is bound to grow at a rate of 50% each year, and may like exceeed this expectation. To stay competitive and ahead businesses need to be able to "play" but at the same time focus on their core-competence (mostly not IT).

Business digitization drives the real-time economy

What motivated us to create layline.io were a number of reallife problems in the area of event-processing, which were largely unaddressed by existing solutions. We deemed these issues so important, that we thought it is worthwhile addressing them with a new product.

  • Real-time volume to increase tenfold in the next few years.
  • Companies struggling to reap transactional value of real-time data (do something useful with it in the first 0- 3 seconds).
  • Companies‘ system architectures solidly migrating to cloud architectures, without proper solutions to support this in all aspects.
  • Lack of actual products to support distributed real-time event processing, instead of having to create custom programmed solution based on development toolkits.
  • Availability of awesome streaming technology like akka and flink, which unfortunately have a steep learning curve and do not allow for complete setup and operations by configuration.

Business versatility and survival, are a result digital maturity and speed

# Can’t I solve these problems by other means?

Yes, but it’s tough, lengthy and will cost you dearly. In the past years, and in the context of the Big Data evolution we have witnessed a myriad of new concepts and truly awesome technologies emerge. Cloud, process distribution, asynchronous processing and many more, just to name a few.

You have seen many cool examples and show cases, for sure. None of them, however, were simple to create and required lots of time and specialized staff and resources.

# Solution

layline.io wants to make this easy by enabling users to

  1. create individual event workflow processing logic
  2. which can be deployed across a distributed processing network (physically, logically and geographically)
  3. which asks to configure and deploy everything without custom coding, and
  4. supports any event-processing scenario from small to super extra large in a highly scalable and resilient environment (or simply on your laptop!)

layline.io provides a solution to integrate real-time and non-real-time event/message-exchange in a relatively easy and configurable way. Time and cost to production are exceptionally low compared to other solutions.

Now on to the show ...

# How it works

# The story in a nutshell

# 1. Creation

Using the web-based Configuration Center, you create a new Project. Within the Project you create 1..n Workflows. Each Workflow represents one event data flow which can range from very simple to very complex. The Project itself merely acts as an organizational container. The Workflow in turn is assembled out of a number of Processors which can be pre-configured in Assets. Assets can be reused in Processors throughout the Project. Assets can also inherit configurations from other Assets of the same kind. Much like class inheritance does.

Projects, together with its Workflows, Assets and other parts, are stored by the Configuration Server. The Configuration Server also provides the web-based Configuration Center.

# 2. Deployment

Once your configuration is ready, you deploy all or a selection of the Workflows to a Reactive Engine. A Reactive Engine runs on a Node. A Node can be either your laptop or a Docker container et al running in a remote Kubernetes cluster. The Reactive Engine can be part of a Logical Cluster of many Reactive Engines running in concert. We call this the "Reactive Cluster" (In fact, a single Reactive Engine could be considered a logical Cluster already). Once the Project is deployed, you can activate it. The Reactive Cluster then takes the designated Workflows into operation. If you have deployed to a Reactive Engine which is part of a cluster of Reactive Engines, then the Workflows are automatically propagated to all the Reactive Engines running within the same logical Cluster.

# 3. Monitoring

You can monitor execution on the Reactive Engine or Reactive Engine Cluster through the web-based Configuration Center. It is possible to tweak operating parameters during runtime, for example how many Workflows should be running in parallel and more. If you need to stop parts of the processing (e.g. for maintenance) you can do so using the Operations part of Configuration Center. You can change how the workload is balanced among Nodes and Workflows.

# 4. Repeat

To change any of the configuration you can simply repeat the process. layline.io allows to inject new and changed Workflows while everything is running to eliminate potential downtime.

# Moving Parts

Let's revisit: layline.io consists of three main components:

# Configuration Server

A process which

  • Serves the Web-based Configuration Center
  • Handles some configuration support services
  • Manages the Project storage

# Configuration Center

A web-based UI which is used for

  • the configuration of layline.io Projects
  • the deployment of Projects to a Reactive Engine / Reactive Engine Cluster
  • the monitoring of one or more Reactive Engine Clusters

# Reactive Engine

A process which

  • executes a Project and Project Workflows
  • is spawned 1..n times on 1..n nodes.

# Support the DevOps process

As outlined above, configuration, deployment and monitoring are done in steps which are in line with the DevOps cycle:

# Features

  • Fast Data
    High-speed and low-latency processing. Leads to smaller hardware and much less cost.

  • Elastic
    Automatically adapts to changing workloads and balances across nodes based on intelligent algorithms. Scale up and out.

  • Connected
    Connects to all popular and not so popular data sources and sinks. Both in real-time and batch.

  • Distributed
    Deploys locally on a single node, or in geographically scattered environments as if it were one system.

  • Immortal
    Nodes take on other Node's work until rejoin.

  • Multi-OS
    Works on current Linux, MacOS and Window operating system versions.

  • Flexible
    Supports any processing and service scenario, no matter how individual by mere configuration.

  • One-click deployment
    Deploy even to a multiple nodes with only one-click.

  • Payload aware
    Not just passing data: Understands payload structure by configuration.

  • Self-balancing
    Auto-balances work across available resources (e.g. Workflows, Engines, Cluster nodes)

  • Streamed processing
    Native stream processing instead of batch

  • Streamed processing
    Native stream processing instead of batch

# Use Cases
