In this section, we will look at Informatica cloud interview questions asked extensively in the job interviews. Informatica cloud integration platform is the best integration platform as a service(iPaaS). It reduces development time and costs by allowing us to integrate enterprise data management technology into our offerings. The user interface of Informatica cloud is user-friendly, and we will have multiple options for configuring our mappings. We can quickly implement any integration with Information Cloud Data. According to a 2019 Gartner report, Informatica has the highest global market share in Integration Platform as a Service(iPaaS). As per ziprecruiter.com, the average salary for an Informatica cloud developer in the US is around $121K per annum. If that is the career you are building and you are preparing for an Informatica cloud developer job interview, the following information will help you prepare.

Informatica Cloud Interview Questions and Answers

1. Define Informatica Cloud?

Informatica Cloud is an ETL and Integration platform providing a web interface to the web developers to access administrator and monitor the tasks by using that web interface. It helps the developers build the solutions that perform the ETL processes between the cloud and on-site solution.

2. What is the primary purpose of the Informatica Cloud?

The primary purpose of the Informatica cloud is to resolve the data integration problem that takes place when we have to move the data from the legacy architecture to the cloud-based architecture. Through the Informatica cloud, we can resolve the issue of handling fragmented data inside and outside the firewall.

3. Explain the Runtime Environment?

The runtime environment is the implementation environment that implements the data integration tasks or application integration tasks. We should have a minimum of one environment setup for running the tasks in our organisation. Generally, it is the server based on the data that gets arranged while processing. We can select either for processing through the Informatica servers or our local servers that remain behind our firewall.

4. What is a Replication Task?

The replication task enables us to replicate the data from the database table or the on-site application to the required target. We can replicate all the data sources rows that modify since the last runtime of the task through the inbuilt gradual processing method of the Replication task.

5. Differentiate Informatica PowerCenter and Informatica Cloud

The web version of Informatica PowerCenter is Informatica Cloud, and Informatica Cloud utilises Informatica PowerCenter capabilities for providing web applications to all the functionalities. Informatica Cloud has the capability to provide more enhanced data integration capability over the cloud. 

6. Explain Cloud Designer?

We can consider the Cloud designer as the equivalent version of the PowerCenter designer. Through cloud designer, we can effortlessly configure the mappings that are ideally the same as how we configure the PowerCenter mappings. Through Cloud designers, we can transform the data through the transformations like Filter transformation, Expression Transformation, etc.

7. Explain Synchronization Task?

The synchronisation task allows us to synchronise the data between the source and the target. We can build a synchronisation task from the IICS UI by choosing the original and the target without using any transformations like in mappings. We can also utilise expressions for transforming the data based on the business logic or use data filters for filtering the data. Without PowerCenter mapping and transformation, we can build the synchronisation tasks like UI guides.

8. Differentiate Synchronization and Replication Task?

In the synchronisation task, you should have an objective for data integration. But, a replication task will establish a target for you. The Replication task replicates a complete scheme and all the tables in it, which is impossible in the Synchronization task. A Replication task has an in-built incremental processing method. In the Synchronization task, we have to handle incremental data processing.

9. Explain Mapping Configuration Task?

Mapping Task or Mapping Configuration Task is similar to a session in the Informatica PowerCenter. We can define the parameters that relate to the mapping. Insert modern session properties for enhancing the performance and configuring the tasks to run on time.

10. Explain Hierarchical Schema in IICS?

Hierarchical Schema is an element where we can upload a JSON or an XML file that specifies the hierarchy of the output data. Hierarchy Parser transformation transforms the input according to the Hierarchical Schema that is related to the transformation.

11. Explain Dynamic Linking

Informatica Cloud enables us to establish a target file at runtime. We can use this feature only in mappings. In the target, we can select the “Create New at Runtime” option. We can choose a static filename that can be displaced with a new file whenever the mapping operates with the same name. We can also create a Dynamic filename such that whenever the mapping runs, we can create a file with the new name.

12. Explain Mapping areas of Cloud designer?

Following are different mapping areas of cloud designer:

  • Transformation Palette: By clicking or by drag and drop, we can add the transformations. 
  • Mapping Canvas: In this area, we will configure the maps. This area is almost similar to PowerCenter Designer.
  • Toolbar: All the tools connected to cancelling, validating, saving, zoom in or out, arranging are available in this mapping area.
  • Properties Panel: The configuration options associated with the transformation or mapping is displayed here. In PowerCenter, we have several tabs that do similar tasks.
  • Status Area: This mapping area notifies us about the status of the tasks displayed.

13. Explain Taskflow?

Task flow is similar to the workflow of the Informatica PowerCenter. Task flow regulates the execution order of the mapping configuration task or the synchronisation task according to the previous task output.

14. Explain Informatica Cloud REST API?

Informatica Cloud REST API provides us with the capability to access the information through Informatica Intelligent Cloud Services. Developers also perform tasks like create, update, delete connections, starting and monitoring jobs, etc.

15. How do we read JSON source file in IICS?

Through the Hierarchy Parser transformation of IICS, we read the JSON files. We have to specify the hierarchy of the output data. Hierarchy parser transformation transforms the input according to the Hierarchical Schema that is related to the transformation.

16. Explain the Differentiator of Cloud Architecture?

The Informatica cloud architecture is multitenant, and the web interface is provided extra attention to the UI/UX. The architecture nature is such a way that if there exist internal informatica systems, we can utilize the advantages of the hybrid solution implementation. Through this architecture, developers concentrate on integration steps in place of running the job on the cloud. 

17. List some essential resources provided by the Informatica Cloud REST API

Some are the broadly used resources are:

  • ActivityMonitor: ActivityMonitor variable  job details are returned.
  • Connection: Connection variable returns the data integration connections.
  • Activity log: This variable returns activity log job details.
  • Schedule: Schedule variable returns schedule details. It helps us in updating or creating the schedules.
  • Job: Task is started or stopped.

Conclusion

Informatica Cloud is the next phase for any enterprise which wants to take their infrastructure on the cloud without moving the data for a developer. Through the above Informatica cloud interview questions, you will be all set to take an Informatica cloud job interview without any burps.
