Smart DIH - Application Life Cycle & Performance

Application Life Cycle

The following diagram represents the Smart DIHClosed Smart DIH allows enterprises to develop and deploy digital services in an agile manner, without disturbing core business applications. This is achieved by creating an event-driven, highly performing, efficient and available replica of the data from multiple systems and applications, platform life Cycle:

Initial Setup

The following steps are required in order to install the Smart DIHClosed Digital Integration Hub. An application architecture that decouples digital applications from the systems of record, and aggregates operational data into a low-latency data fabric. system

  1. Hardware and Network Setup - Either on-premise or cloud

    1. Network Configuration - Virtual Network, Routers, VPN

    2. Compute Resources - including cpu/memory, Disk

    3. Security Setup - Firewalls, Gateways, access rights

  2. SORClosed System of Record. This is an information storage and retrieval system that stores valuable data on an organizational system or process. This record can contain multiple data sources and exist at a single location or multiple locations with remote access. Agent Installation - File and database configuration

  3. KubernetesClosed An open-source container orchestration system for automating software deployment, scaling, and management of containerized applications. and Application Installation - This is where the controller, data-grid and streaming (KafkaClosed Apache Kafka is a distributed event store and stream-processing platform. Apache Kafka is a distributed publish-subscribe messaging system. A message is any kind of information that is sent from a producer (application that sends the messages) to a consumer (application that receives the messages). Producers write their messages or data to Kafka topics. These topics are divided into partitions that function like logs. Each message is written to a partition and has a unique offset, or identifier. Consumers can specify a particular offset point where they can begin to read messages.) are provisioned

  4. In SpaceDeckClosed GigaSpaces intuitive, streamlined user interface to set up, manage and control their environment. Using SpaceDeck, users can define the tools to bring legacy System of Record (SoR) databases into the in-memory data grid that is the core of the GigaSpaces system.

    1. Configure the IDPClosed An identity provider, or IDP, stores and manages users' digital identities. IDP and SSO can work together to authenticate users., Roles and Service Accounts (performed by the Admin)

    2. Setup Data Sources - point to the SOR agent and setup connection configuration

    3. Set up Spaces - define the data-grid spaces for holding the data

    4. Set up Pipelines - define the data that goes into the data-grid

    5. Set up Services - define the micro-service/s that consume the data from the data-grid (either by SQL or Code) and the APIs

    Refer to our SpaceDeck User Guide for comprehensive information.

Control, Logging & Monitoring

Control of Smart DIH is managed through SpaceDeck. Platform logs can also be accessed via SpaceDeck. For more advanced logging queries and ELK stack can be attached to the pods (components) logs. And example of such a service is Amazon OpenSearch.

Monitoring can be performed by both utilizing the tools that integrated within SpaceDeck and using dashboards in GrafanaClosed Grafana is a multi-platform open source analytics and interactive visualization web application. It provides charts, graphs, and alerts for the web when connected to supported data sources.. Upon startup a few dashboards are uploaded to Grafana including data-grid metrics.

Refer to our SpaceDeck User Guide for comprehensive information.

Updates & Upgrades

The user can update the Smart DIH platform in the following ways:

  1. Add Spaces

  2. Update/Add pipelines

  3. Update/Add services

  4. Upgrade Kubernetes

  5. Upgrade the platform

Refer to our SpaceDeck User Guide and Smart DIH Kubernetes Installation Guide for additional information.


Many of the Smart DIH components contain the appropriate redundancy and are spread across multiple availability zones. The following components maintain this ability:

  1. Data-Grid - Special primary/backup technology maintains high availability of the cached data. The Kubernetes nodes are setup with anti-affinityClosed This describes the relationship between VMs and hosts or when related to Kubernetes between pods. Anti-Affinity will keep VM and hosts separated and using Kubernetes an anti-affinity rule tells the scheduler not to place the new pod on the same node if the label on the new pod matches the label on another pod. In this case, anti-affinity allows you to keep pods away from each other. It also allows you to prevent pods of a particular service from scheduling on the same nodes as pods of another service that are known to interfere with the performance of the pods of the first service. mode for the primary and backup copies.

  2. ZookeeperClosed Apache Zookeeper. An open-source server for highly reliable distributed coordination of cloud applications. It provides a centralized service for providing configuration information, naming, synchronization and group services over large clusters in distributed systems. The goal is to make these systems easier to manage with improved, more reliable propagation of changes. - Zookeeper that holds some configurations needs a quorum of instances that span over multiple zones.

  3. Kafka - Kafka is configured by default with a replication factor higher than one. So there are always additional copies of the data in multiple zones.

  4. FlinkClosed Apache Flink is an open-source, unified stream-processing and batch-processing framework developed by the Apache Software Foundation. The core of Apache Flink is a distributed streaming data-flow engine written in Java and Scala. Flink executes arbitrary dataflow programs in a data-parallel and pipelined manner. (in the transformation layer)- Launching a few instances of the task manager ensures that tasks can be run continuously.


GigaSpaces IMDGClosed In-Memory Data Grid. A set of Space instances, typically running within their respective processing unit instances. The space instances are connected to each other to form a space cluster. The relations between the spaces define the data grid topology. Also known as Enterprise Data Grid - EDG (in-memory data grid) is a technology that manages data queries from the data-grid. Read and writes queries are executed in a few milliseconds (depending on the complexity). Due to this, the services accessing the data-grid can benefit from its high performance.
