Netezza To Snowflake

1. The Need to Migrate Data from Netezza to Snowflake Netezzawas introduced in 2003 and became the first data warehouse appliance in the world. Subsequently, there were many “firsts” too – 100 TB data warehouse appliance in 2006 and petabyte data warehouse appliance in 2009. Netezzahas had an amazing run, with unmatched performance due to its hardware acceleration process in field-programmable gate arrays (FPGA). This could be fine-tuned to process intricate queries at blistering speed and scale. Data compression, data pruning, and row-column conversion were all handled optimally by FPGA.

2. During the lifetime of Netezza, various versions have been launched and all of them have provided high value to the users with simplified management, data pruning, and no need for indexing and partitioning of data. Then, why would users want to migrate data fromNetezza to Snowflake? The cloud-based data warehouse revolution made a huge difference to Netezza as IBM withdrew support. New hardware has not been released since 2014. By doing so IBM has forced Netezza users to abandon the appliance and opt for cloud-based data warehousing solution Snowflake. There are many benefits of Snowflake for those wanting to shift from Netezza to Snowflake. Snowflake is a premium product, providing a great deal of performance, scalability, and resilience, more than other cloud-based data warehouse solutions.  

3. Additionally, there are many advantages of shifting to the cloud and Snowflake for data management. ·        Affordable – Enterprises do not have to invest in additional hardware and software. This is very critical for small industries and start-ups. In this pricing model, users can scale up or down in computing and storage facilities and pay only for the quantum of resources used. ·        Reliability – Reliability and uptime of server availability are mostly in excess of 99.9%. ·        Deployment speed – Organizations have the leeway to develop and deploy applications almost instantly because of access to unlimited computing and storage facilities. ·        Economies of scale – When several organizations share the same cloud resources the costs are amortized for each of them, leading to economies of scale. ·        Disaster recovery – When there is an outage in primary databases, the secondary databases in the region are automatically triggered and users can work as usual. When the outage is resolved, the primary databases are restored and updated automatically.          

4. There are two steps in any Netezzato Snowflakedata migration strategy. The first is the lift-and-shift strategy which is used when there is timescale pressures to move away from Netezza with the need to move highly integrated data across existing data warehouse. This is also relevant when a single standalone and independent data mart has to be migrated.

5. The second is the staged approach. This is applicable when many independent data marts have to be moved independently. The focus here is on new development rather than reworking legacy processes. Choosing between the two largely depends on such factors as timescale, number of data resources, and types of data types.
