For the instances where for whatever reason, a Talend job does not always connect to a backend service layer - database, web service, ftp, salesforce, dropbox - on the first try, the job can be modified to retry the connection before failing the job. This solution shows a simple design to handle intermittent connection failures.
Data warehousing and ETL processes usually repeat common patterns across different data domains (databases, tables, subject areas etc...). One such pattern is copying data from a transactional system to Hadoop or some other data platform (Teradata, Oracle DBs) to create 'images' of those systems for downstream processing. Because these processes are repeated many times over in the design & construction of data warehouses, it is best to create repeatable patterns that reduce future technical debt in terms of support, maintenance and updates costs.
