Cloud Integration: Stages, Options, Timeline, and Costs

Cloud Application Integration Guide - ScienceSoft

ScienceSoft has been providing cloud application development and integration services since 2012.

Cloud Integration: the Essence

The integration of cloud-hosted applications with other cloud or on-premise software of medium complexity usually takes around 8-12 months, including steps like planning and design, implementation and testing. The project requires a team of a project manager, a business analyst, an integration architect, developers, QA and DevOps engineers.

In software development since 1989, ScienceSoft helps build reliable, secure and convenient cloud-based integrations between custom and/or commercial systems.

Cloud App Integration Roadmap

The steps of the cloud application integration process and their timelines will differ depending on the number of applications integrated, their architecture, required legacy software modification, integration approach, complexity of security and compliance requirements, and more. Below are described the typical steps we at ScienceSoft take to perform cloud application integration.

Best practice: We also often define business metrics to help our clients measure and understand the integration initiative success (e.g., improved order processing/delivery time, reduced transaction errors, reduced time to introduce a new software solution, etc.).

Integration approach selection

ScienceSoft's team decides on an appropriate cloud app integration approach from 4 major types described below. The choice between direct and mediated integration approaches will depend on the number of application to be integrated, planned short-term and long-term investments, overall IT strategy (for enterprises)/business strategy, non-functional requirements to the integrated system (performance, availability, security), the necessity to integrate with legacy software, and more.

Direct (point-to-point) integration

  • Using tools and/or out-of-the-box integration provided by applications’ vendors.
  • Using custom code.

Mediated integration

  • Using Enterprise Service Bus (ESB). ESB is a central mediator (integration server) that takes over the responsibility for communication between services and undertakes message processing, transformation/modification, and routing, transaction management, process choreography, security management. Special adapters allow the applications to communicate with ESB translating or transforming the message data (e.g., XML to JSON, JMS to HTTP, XML to Java objects).
  • Using an integration platform as a service (iPaaS). An iPaaS solution is a set of cloud services that often includes API management, orchestration, messaging and event management services.

It’s a rare case when a single integration pattern fits all the required connections when several apps are to be integrated. So, ScienceSoft often uses a combination of several integration approaches.

Optional: evaluation and comparison of tech stacks for the selected integration approach

ScienceSoft's BA and solution architect shortlist 2-3 preferable integration tech stacks (e.g, for an ESB-based integration – Talend ESB and SAP PI, for iPaaS-based integration – Azure iPaaS or Informatica iPaaS) and rate strengths and weaknesses of each option. Together with the project stakeholders, we decide on the most feasible option with the best strategic potential.

Best practice: When our clients also need their external partners to connect, we always keep in mind to discuss if their partners have or ready to employ the required infrastructure and skills to use the chosen integration technologies and support the planned communication standards.

Step 2. Implementation and testing

Duration: 5-9 months to develop a new integration solution

The steps of this stage will differ depending on the chosen integration approach. Below, you can find exemplary scenarios for two most popular integration approaches.

Direct integration

  • Designing and installing custom APIs or implementing ready-to-use APIs.

Mediated integration

  • Building or buying a glue layer (message processor/ESB) that will handle message routing, modification, aggregation and changing the mapping of the data.
  • Creating connections – select or build adapters for your applications to communicate with the glue layer.
  • Orchestrating integration:
    • Configuring triggers for requests sent to the service.
    • Configuring invokes for requests sent from the service to the target.

The QA team works on:

  • Verification of all uni- or bidirectional queries between the connected interfaces.
  • Checking the completeness of distributed transactions.
  • Approval of appropriate exceptions handling.
  • Assuring the work of the failover and recovery mechanisms.
  • Checking how well the integrated system works within established bandwidth limitations.
  • Checking how good the system components are at fail-free processing of large data sets and handling an increased number of requests.

Step 3. Integrated system support and evolution

The support team monitors the integrated system performance and handles its scale-ups (the number of users) and scale-outs (the number of the integrated applications).
