A data cloud is a centralized repository that allows an organization to store vast amounts of raw data in its natural format, whether structured or unstructured, until it is needed. With a data cloud, any type of data - from social media feeds and website logs to machine data from IoT sensors - can land in the same place without worrying about structuring it at the outset for a specific purpose.
The Evolution of Data Lake and Analysis
Traditionally, businesses collected and stored data in highly specialized databases tailored for specific uses like transactions or analytics. But modern data volumes and types have grown far more diverse. Streaming data from websites, mobile apps, IoT devices, and more now make it difficult for businesses to predefine rigid schemas for where different data should reside.
Moreover, the questions companies want to answer with their data are also continually evolving as new products, services, and business needs emerge. Having data siloed away in separate systems limits the insights organizations can derive, as data cannot be combined and analyzed together holistically.
Business users and data scientists can directly access raw Data Lake through analytical tools and APIs to perform experiments and analytics without IT intervention.
The Key Attributes of a Data cloud
Several key attributes define data clouds and differentiate them from traditional data warehouses:
- Raw data is stored in its native format - Data lands in the lake just as it is ingested from various sources without needing to first structure it for a specific query workload. This "raw" approach maximizes flexibility.
- Flexible schemas - Structured, semi-structured, and unstructured data coexist seamlessly in a data cloud without rigid constraints on columns or record formats. Schemas can evolve over time.
- Supports multiple workloads - The same raw data can support diverse analytic workloads, from SQL queries to artificial intelligence modeling. New applications and questions can be enabled.
- Scalable storage - Massive volumes of data from numerous sources can be accommodated cost-effectively using scale-out storage such as object storage. Petabytes or exabytes can be housed.
- Self-service analytics - Business analysts and data scientists can independently access raw data for exploratory analysis using appropriate tools, without having to rely on IT for custom extracts and infrastructure setup.
Benefits of Data clouds for Organizations
There are several key ways data clouds help organizations derive more value from their rapidly growing collections of data:
Agile Analytics and Insights
With the freedom to store all data in its raw form centralized, insights can be discovered from unforeseen analytic workflows and ad hoc queries. New questions can be answered quickly by analysts, data scientists and engineers without waiting for IT. This accelerates the insights lifecycle.
Holistic, Cross-Departmental Views
Since data clouds allow all types of structured and unstructured data from across an organization to commingle in one place, previously siloed information can now be combined. Powerful insights may emerge from blending together disparate yet related datasets.
Cost Savings and Simplicity
Data clouds eliminate expensive extract, transform and load processes required to migrate data between specialized databases, which also introduces complexity. Raw data is loaded once at source and then serves many use cases over its lifecycle from a single landing zone, lowering total cost of ownership.
Support for AI/ML Initiatives
For artificial intelligence and machine learning projects, having all organizational data accessible in its raw form in one pipeline is invaluable. AI algorithms can be developed and tested against comprehensive datasets for more sophisticated pattern detection and predictive accuracy.
Governance and Compliance
Though data clouds weaken pre-ingestion controls compared to structured datastores, tools exist for auditing access, enforcing policies on data use, classifying sensitivity, and compliance with regulations like GDPR as data moves from its raw state to downstream analytical workflows.
In summary, data clouds represent an evolution from application-centric storage silos to a more versatile framework that maximizes what businesses can achieve from their ever-growing troves of information. Their ability to accommodate all types and sources of data in its native format fuel increasingly dynamic data and analytics strategies.
Challenges of Data clouds
While data clouds offer significant benefits, certain challenges still require ongoing attention from organizations adopting this new approach:
Data Discovery and Search
With raw data of mixed quality and structure stored without imposed schemas, finding relevant data for particular uses becomes harder. Solutions range from semantic layer tools to machine learning-powered data catalogs and search.
Data Quality
Ingested data may contain errors, duplicates, or inconsistencies that reduce trust in analyses if not detected and resolved. Solutions include profiling raw data and building quality checks into ETL pipelines.
Security and Governance
As data from numerous sources accumulates in a single platform, security risks also increase if access is not carefully controlled. Auditing, user management, data classification and masking solutions provide governance.
Infrastructure Demands
Serving different analytics workloads from huge volumes of raw data places load on compute, storage, memory and networking resources that must be properly provisioned and tuned.
Integration with Existing Systems
Data clouds must work harmoniously alongside existing data platform investments like data warehouses, especially around extraction workflows and allowing results to flow both ways.
Skills Shortage
Analyzing and preparing raw data for use requires new skills in data engineering, architecture, data science and data visualization that some companies may lack and find difficult to hire for in a constrained talent market.
while data clouds introduce additional management challenges, employing best practices in data quality, security, infrastructure and upskilling the workforce allows organizations to reap the full rewards of these new data-driven platforms over time. With the right focus, they more than empower the analytics potentials of digital transformation.
