Cloud SAAS applications are managed by the providers behind the scenes with little or no downtime. High availability, replication, disaster recovery, upgrades, and maintenance are completely seamless to the end-user.Enterprise Data StrategyEnterprise data consists of multiple sources with various formats such as structured, semi-structured, unstructured, JSON, XML, and many more. Unified Data Service Layer uses multiple data sources from different storage points to gather, analyze, and present results. The performance of the service layer depends on reliable processing, storage, and retrieval from various data without latency. Cloud offers enterprise data eco-system for the entire business operations to store various data formats, compute resources needed to bring back results with no latency, and present unified results set within reasonably expected times. Data storages for different formats store and process information differently, so resources can be allocated according to the individual storage needs to fine-tune and keep results in sync.Data Quality and GovernanceWith data growing and processed at a rapid rate, Data Quality plays a vital role in maintaining data accuracy and reliability in operations, decision making, and planning. Data Governance becomes more and more challenging with silos of data all over the enterprise, getting complicated maintaining catalogs, glossary, and access control.Cloud data platform makes it easier to discover existing and new data, maintain updated catalogs, develop business glossaries, data dictionaries, create policies, and democratize data Cloud environment can replicate data across multiple sites or regions with no data loss, offering instant failover during a disaster recovery situationby delivering it into the right hands to enable quick business decisions. Ensuring Data Quality with automated checks and balances creates reliability and higher predictability of quality. Establishing data lineage and recording transformations from source to end becomes manageable. Data discovery for unstructured documents for big data platform on the cloud becomes relatively easier without compromising production availability, operations, and delivery.Data SecurityAs most businesses deal with customer and sensitive information, Data security is not only critical to meet compliance but also to the existence of the organization. Securing data without affecting performance is a challenge with on-premise systems. Cloud offers Data Security at various levels­encryption at rest and transport during delivery pipelines, machine (IP) level access restriction, LDAP authentication, multi-factor authentication, contextual access control, and role-based user security.Data ScienceData Science is becoming more and more popular, especially with Artificial Intelligence and Machine Learning initiatives leading the way. Machine learning models requireaccess to several data assets including big data for deeper learning and insights across the enterprise. These programs are memory intensive, require high memory, and compute resources during peak loads. Cloud provides dynamic auto-scaling avoiding bottlenecks for resource pooling. Cloud enables automation and operationalization of AI/ML models creating business value.Data Replication for Global EnterpriseFor traditional data environments, data replication presents challenges with time, costs, and network limitations. This is a huge problem for an enterprise with a global presence that needs data replication and synchronization across multi regions both domestic and international.Cloud environment can replicate data across multiple sites or regions with no data loss, ofering instant failover during a disaster recovery situation. Data acquired through various sites and regions across the world can be synchronized instantly to offer the same unique set of data regardless of where the queries originate.
