Colleagues planning data ingestion before migrating to cloud.

With the growth of enterprise data, businesses are facing a digital challenge. Traditional and legacy on-premises databases can’t address today’s data volume, variety and velocity. Data warehouses and data lakes can’t keep up with big data in the public cloud. A recent study suggests that almost 73% of enterprises have failed to provide any business value from their digital transformation initiatives.1

Migrating to Cloud

Many businesses are moving to cloud-based data warehouses and cloud data lakes as part of their cloud data migration strategy. This helps modernize their data and analytics and enables digital transformation. But it doesn’t solve the roadblock of managing data ingestion in cloud environments. And it doesn’t address increasing cloud costs. How can an enterprise effectively manage and hydrate their cloud data lakes and data warehouses from various sources? Also, how can they lift and shift or rehost their data in the public cloud?

Organizations have large volumes of data in various siloed sources. These data sources may include files, databases, change data capture (CDC) sources, streaming data and applications. They need to move this data into a cloud data lake or cloud data warehouse quickly and efficiently. They may also need to move data into a messaging system. Such moves make data available for business intelligence (BI), advanced analytics, real-time streaming analytics, and artificial intelligence (AI) or machine learning (ML) projects. Companies also need to efficiently and accurately ingest large amounts of data in the public cloud. Data ingestion at scale needs to come from various sources, including both batch and streaming. And the approach needs to be unified, using intelligent, automated tools. This helps avoid issues that come from manual approaches like hand-coding.

Seven Common Data Ingestion Challenges

Data ingestion is designed to resolve the challenge of hydrating your data warehouse and data lake in cloud environments. Here are seven common data ingestion challenges:

  1. Out-of-the-box connectivity: Data diversity causes many analytics and AI projects to fail. Building individual connectors for so many data sources isn’t feasible. Writing code requires significant time and effort. Organizations need pre-built, out-of-the-box connectivity. This lets them easily connect to various data sources at scale and improves productivity for data engineers. Sources of data in the data pipeline can include databases, files, streaming data and applications — including initial and CDC load.
  2. Real-time monitoring and lifecycle management: It’s challenging to monitor data ingestion jobs manually. You need to be able to detect anomalies in the data and take necessary actions. Organizations need to infuse intelligence and automation in their data ingestion processes. This lets them automatically detect ingestion job failures and set up rules for remedial action.
  3. Manual approaches and hand-coding: The global data ecosystem is growing more diverse every day. And data volume is exploding. Writing code to ingest data is difficult and inefficient. Manually creating mappings for extracting, cleaning and loading data in the data pipeline is just as challenging, impacting the productivity of data engineers.
  4. Schema drift: Sources and targets may change data aspects like fields and columns over time. The result? Schema drift. It is an inevitable byproduct of the decentralized and decoupled nature of modern data infrastructures. Most data-producing applications operate independently and go through their lifecycle of changes. As systems change, so do the data feeds and streams they produce. This constant flux creates chaos. It keeps companies from developing reliable, continuous ingestion operations.
  5. Speed: With the explosion of new and rich data sources, enterprises find it challenging to get value from diverse data. Sources include smartphones, smart meters, sensors and other connected devices. When organizations implement a real-time data ingestion process, things get even more difficult. That’s because it requires data to be updated and ingested rapidly.
  6. Costs: Proprietary tools that support a variety of data sources can be very expensive. It’s also costly to maintain in-house experts to support data ingestion pipelines. When they can’t make data-led decisions quickly, businesses face disruption and suffer lost opportunities.
  7. Legal data compliance: Compliance makes it difficult for companies to manage their data according to regulatory requirements. This is especially true for global companies. For example, European companies need to comply with the General Data Protection Regulation (GDPR). U.S. healthcare data is affected by the Health Insurance Portability and Accountability Act (HIPAA). U.S. companies using third-party IT services require auditing procedures like Service Organization Control 2 (SOC 2).

Selecting the Right Data Ingestion Tool for Your Business

Now that we know the various types of data ingestion challenges, let’s explore how to evaluate the best tools.

Data ingestion is a key capability for any modern data architecture. A proper data ingestion infrastructure allows the ingestion of any data at any speed, using scalable streaming, file, database and application ingestion. It delivers comprehensive and high-performance connectivity for batch or real-time streaming data. Below are five must-have attributes for any data ingestion tool to help you future-proof your organization:

  1. High performance: When big decisions are needed, it’s important to have the data available how and when you need it. With an efficient data ingestion pipeline, you can cleanse your data or add timestamps. This can be done during ingestion with no downtime. You can ingest data in real-time using Kappa architecture and batch using a Lambda architecture.
  2. Improved productivity: Efficiently ingest data with a wizard-based tool. This requires no hand-coding. It allows you to move data onto cloud data warehouses with CDC. This ensures that you have the most current, consistent data for analytics.
  3. Real-time data ingestion: Accelerate ingestion of real-time log, CDC and clickstream data. Data can be ingested into Kafka, Microsoft Azure Event Hub, Amazon Kinesis and Google Cloud Pub/Sub. This helps deliver real-time actionable analytics.
  4. Automatic schema drift support: Detect and automatically apply schema changes from the source database onto the target cloud data warehouse. This lets you meet cloud analytics requirements.
  5. Cost efficient: Well-designed data ingestion should save your company money and keep your cloud costs down. It does this by automating processes that are costly and time-consuming. Data ingestion can be significantly cheaper if your company isn’t paying for the infrastructure or high skilled technical resources to support it.
