SnapLogic Best Practices: Deploying Projects Between Phases

[update – check out what’s new in our Spring 2016 release – the Metadata Snaps are also useful for Lifecycle Management requirements]

One of the areas our services team and partners spend time with customers early in a SnapLogic Elastic Integration Platform deployment is on deploying from one project phase to the other (Dev -> QA -> Prod). There are a number of different configuration options. In this post, I’ll describe one. First a few assumptions:

  • The enterprise Lifecycle Management feature is not implemented in this example
  • The phases that are in use are Development, QA and Production
  • Each phase in use is being managed at a project level as a separate project with in a single Organization Setup
  • The users have the necessary permissions to perform the operations described in this post
  • The enhanced account encryption feature is not in use in the current SnapLogic Org

Ultra Pipelines: Performance, Management and Monitoring

In my final post in this series on SnapLogic Ultra Pipelines I’m going to cover the three pillars for successful implementation: performance, scaling and high availability.

  1. Performance: Performance of an Ultra Pipeline largely depends on the response times of the end-system applications that the task is connecting to. An Ultra Pipeline containing a large number of high latency endpoint Snaps can observe a congestion of documents, building all the way up through the upstream Snaps to the feedmaster, until the feedmaster queue can no longer hold the messages. This can be avoided by either creating multiple instances of the Ultra Pipeline task or by using the Router Snap to distribute the document load. Multiple instances of an Ultra Pipeline will ensure that even if one instance is slow, others are available to consume documents and keep the feedmaster queue flowing. Likewise, a Router Snap can be used in each instance of the pipeline to distribute the documents across multiple endpoint Snaps, to improve the performance and add parallel processing capability to an instance. This is in addition to the built-in parallel computation capability of a pipeline which implies that at a given point in time, each Snap in a pipeline is processing a different document.
  2. Scaling: Scaling can be attained by increasing the number of instances in an Ultra Pipeline task. The total number of instances required for an Ultra Pipeline task is a direct function of the expected response time, the resource utilization of the node when a single instance of the task is running and the functional load on the Snaplex from other pipeline runs. When the execution nodes are highly utilized, adding more execution nodes allows the instances of the task to be distributed horizontally and scaled out across the Snaplex.
  3. High availability: In order to avoid service disruption and to allow high availability, it is highly recommended to use a load balancer with two feedmasters and two execution nodes as the minimum architecture for Ultra Pipeline setup. Such an architecture can also be used to avoid a single point of failure from a feedmaster or execution node.

Designing Ultra Pipelines: Types of Views

In my first post on SnapLogic Ultra Pipelines, I began to review aspects to consider when designing these low-latency pipelines. Once you’ve determined the right number of views, you need to determine the type of views. The unconnected views in an Ultra Pipeline act as the gatekeepers of the task, receiving and returning documents from the external applications.

Designing Ultra Pipelines

Ultra Pipeline tasks are used to implement real-time web service integrations which require expected response times to be close to a few sub seconds. In the first series of posts I’ll outline some of the key aspects of designing Ultra Pipelines. In the second series of posts I’ll focus on monitoring these low-latency tasks.

Setting up Ultra Pipelines
Ultra Tasks let a pipeline, known as an Ultra Pipeline, continuously consume documents from external sources.

Because Ultra Pipelines are analogous to web service request/response architecture, the following aspects should be considered in designing Ultra Pipelines in SnapLogic. Continue reading “Designing Ultra Pipelines”
