Cloud Data Lake

Cloud Data Lake – Let’s start with a discussion of what data lakes are and then where they fit in as an integral part of your overall data engineering ecosystem. So what is a data lake? Well, it’s a very broad term, but it generally describes a place where you can safely store different types of data of all scales for processing and analysis.

Data lakes are typically used to drive data analysis, data science and ML workloads or batch and stream pipelines. Data lakes can accommodate all types of data. Finally, data lakes are portable on-premises or in the cloud.

In the middle of this diagram, the data lake here is the Google Cloud Storage buckets. It’s your one-stop shop for raw, stable, and highly available data. Be aware that Google Cloud Storage is your only option for data legs on GCP, it’s one of several good options to be as data, but it’s not the only one.

That’s why it’s so important to first understand what you want to do and then figure out which solutions best suit your needs.

Your database will generally be the single point of collection for all of your raw data. I like to think of it as a stable, everything is collected here and then shipped elsewhere.

Now that data can end up in many other different places, like a transformation pipeline that cleans it up and moves it into the data warehouse. And then it’s read by a machine learning model, but it all starts with getting that data into your data lake first.

In this data lake article, we’ll focus on the Cloud Storage product that makes up your data lake.

Data Lake: Design Principles & Best Practices

Google Cloud Storage is the essential storage service for working with data, especially unstructured data. Let’s dive into why Google Cloud Storage is a popular choice for a data lake.

As a data engineer, you need to understand how cloud storage achieves these similar capabilities and when to employ them in your solutions.

Many of the amazing properties of cloud storage have to do with the fact that it is ultimately object storage and all other features are built on top of that foundation. The two main groups in the cloud store our buckets and objects.

Cloud Data Lake

So buckets are containers for our data purposes, buckets are identified by a globally unique name. This means that once a name is assigned to a block, no one else can use that block until that block is deleted and that name is released. Having a global namespace for buckets greatly simplifies finding any specific bucket. When the bucket is created it is associated with a specific region or multiple regions, choosing a region close to where the data will be processed will reduce latency.

Getting The Most Out Of Cloud Data Lakes

When an item is stored, the cloud storage replicates that item, then keeps track of the replicas, and if one is lost or corrupted, it automatically sends a new copy.

For a regional block, as you would expect, items are repeated across zones within the same region.

Objects are stored with metadata, metadata is information about that object. Additional cloud storage features use the metadata for purposes such as access control, compression, encryption, and lifecycle management of these objects and stores. This feature uses the item’s metadata to determine when to delete that item. When creating a bucket, you have to make several decisions. The first is the location of that block, the location is set when a block is created and can never be changed.

Cloud storage uses the bucket name and object name to simulate a file system. Here’s how it works: the bucket name is the first term in the URI, is appended with a slash, and then matches the object name. The object name allows the slash character as a valid character in the name, the very long object name containing slash characters. It looks like a file path system, although there is only one name, in the example shown the name of the bucket is “declass”. The object name is “de/modules/O2/”, the slashes are just characters in the name.

Google Cloud Storage can be accessed using the file access method, which, for example, allows you to use a copy command from your local file directory to Google Cloud Storage. You can use the gsutil tool or the Google storage utility to do this, cloud storage is also available on the web. The site for this is and it uses TLS or HTTPS to transport your data, which protects the credentials as well as the data being transferred.

So, as you can see, Cloud Storage is object storage for businesses of all sizes. Save any amount of data. Retrieve it as many times as you like. Cloud Storage has a growing list of storage locations where you can store your data with various automatic redundancy options. In addition, Cloud Storage has many other object management features.

First, let’s take a quick look at the Apsara big data platform, hereinafter referred to as the Apsara platform. The Apsara platform consists of AI-PAI (machine learning and deep learning platform) and the big data platform. In addition to E-MapReduce (EMR), engines such as MaxCompute, DataHub, Realtime Compute and Graph Compute are also available.

The data lake was proposed 15 years ago and has become popular in the last two or three years. In Gartner’s Magic Quadrant, data lake technology has significant investment and research value.

What is a data lake? Previously, we used data warehouses to manage structured data. After the advent of Hadoop, a large amount of structured and unstructured data was stored in HDFS. However, as the data is aggregated, some data may not have appropriate application conditions when collected. So we simply store the data first and then consider development and mining when business needs arise.

As the amount of data increases, we can use object storage services like OSS and HDFS for unified storage. We can also consider choosing different computing scenarios, such as ad hoc queries, offline computing, real-time computing, machine learning, and deep learning. In different computing situations, you can still choose different engines. So you need to have an integrated operation for different situations like auditing, authorization, auditing and accounting system.

The first part is data acquisition (the leftmost part in the figure), which is mainly used to obtain relational databases. User data flows to unified storage. Various compute services are used for data processing and computation. At the same time, the computation results are applied to the AI ​​analytics platform for machine learning or deep learning. Finally, the results are used for commercial purposes. Features like search and source data management add value to the data. In addition to compute and storage, a number of control and monitoring measures are required.

More than 10 years have passed since the birth of big data technology. From the beginning, everyone created open source software at their own IDC. With the continuous growth of the industry and the rapid accumulation of data, business traffic changes very quickly and can even explode.

The supply cycle for real estate IDCs is too long to meet the needs of rapidly growing businesses. During the day, most computing tasks are ad hoc queries. At night, it may be necessary to increase some resources for computing offline reports. These conditions make it difficult to match the computing power in the
