  Improving the performance of AWS Glue jobs involves several strategies that target different aspects of the ETL (Extract, Transform, Load) process. Here are some key practices. 1. Optimize Job Scripts Partitioning : Ensure your data is properly partitioned. Partitioning divides your data into manageable chunks, allowing parallel processing and reducing the amount of data scanned. Filtering : Apply pushdown predicates to filter data early in the ETL process, reducing the amount of data processed downstream. Compression : Use compressed file formats (e.g., Parquet, ORC) for your data sources and sinks. These formats not only reduce storage costs but also improve I/O performance. Optimize Transformations : Minimize the number of transformations and actions in your script. Combine transformations where possible and use DataFrame APIs which are optimized for performance. 2. Use Appropriate Data Formats Parquet and ORC : These columnar formats are efficient for storage and querying, signif

Cloud+ certified professionals ensure that proper security measures are maintained for cloud systems, storage, and platforms to mitigate risks and threats while ensuring usability. The exam is geared toward IT professionals with 24 to 36 months of experience in IT networking, network storage, or data center administration. It is recommended that CompTIA Cloud+ candidates have CompTIA Network+ and/or CompTIA Storage+ Powered by SNIA certification.

It is further recommended that Cloud+ exam candidates have familiarity with any major hypervisor technologies for server virtualization, though vendor-specific certifications in virtualization are not required.
