Moreover, yes, it is serverless as It can scales up/down as our query requirement, and We have to pay per query.Amazon Athena also supports various format also like Parquet, Avro, JSON, CSV, etc. The figure shows the overview of the technical architecture of the big data platform. All Infra Design handled by some third party services where the code runs on their containers using Functions as a Service, and they further communicate with the Backend as a service for their Data Storage needs. Glue also allows us to get the ETL script in python or scala language and We can add our transformation logic in it. immediately in our AWS Lambda Function. Data virtualization enables unified data services to support multiple applications and users. However, most designs need to meet the following requirements […] Big data can be stored, acquired, processed, and analyzed in many ways. Keep and safeguard an archive of big data architecture products. From there, you can have more concrete point of view, what the big-data … Let’s say we have a Web Application hosted on our On-Premises or Cloud Instance like EC2. So We were always paying for EMR Cluster on per hour basis. Should be scalable to store multi years data at low cost and also file type constraint should not be there. Now Let’s see What Serverless MicroServices offers us: You will be charged only for the execution time of microservice which is used by any type of client. The solution requires a big data pipeline approach. Low level code is written or big data packages are added that integrate directly with the distributed data store for extreme-scale operations and analytics. In Real-time Analytical Platforms, Data Sources like Twitter Streaming, IoT Analytics, etc push data continuously, So the First task in these platforms is to build a unified Data Collection Layer where we can define all these Data Sources and write it to our Real-time Data Stream which can be further processed by Data Processing Engines. Let’s see various points which we can consider while setting our Big Data based Platforms. This can be used to store big data, potentially ingested from multiple external sources. So The Challenge in Batch Job Processing is that we don’t know how much data we are going to have in next increment. So What we do earlier is deploy a Spark Job on our EMR Cluster which was listening to AWS SNS Notification Service and use the Cobol layout to decode the EBCDIC to parquet format and perform some transformations and move it to our HDFS Storage. Analytics & Big Data Compute & HPC Containers Databases Machine Learning Management & Governance Migration Networking & Content Delivery Security, Identity, & Compliance Serverless Storage. With the help of OpenFass, it is easy to turn anything into a serverless function that runs on Linux or windows through Docker or Kubernetes. Amazon Athena is very power querying service launched by AWS, and we can directly query our S3 data using Standard SQL. So Our Batch Data Processing Platform should be scaled automatically, and also Serverless architecture will also be cost efficient because as we know that Batch Jobs will run hourly or daily etc. Example: Serverless ETL platform like Glue launches the Spark Jobs according to the scheduled time of our ETL Job. Serverless Querying Engine for exploring the Data Lake and it should also be scalable up to thousands & more queries and charge only when query is executed. But the amount of time you have available to do something with that data is shrinking. So While doing this stuff on Real-time Stream, We need a Data Processing Platform which can process any amount of data with consistent throughput and writes data to Data Serving Layer. For Reporting Services, We can use Amazon Athena too by scheduling them on AWS Cloud Dataflow. The ‘Big Data Architecture' features include secure, cost-effective, resilient, and adaptive to new needs and environment. Yet there’s no getting away from the fact that governance is essential, for both regulatory and business reasons. However, as we know in the world of Big Data, Dynamic Scaling and Cost Management are the keys factors behind the success of any Analytics Platform. In order to clean, standardize and transform the data from different sources, data processing needs to touch every record in the coming data. Cloud Scale Storage is the critical point for the success of any Big Data Platform. Object Storage service like AWS S3 which is highly scalable and cost-effective. The NIST Big Data Reference Architecture is a vendor-neutral approach and can be used by any organization that aims to develop a Big Data architecture. Catalogue Service which should be updated continuously as we receive data in our Data Lake. When big data is processed and stored, additional dimensions come into play, such as governance, security, and policies. And many more use cases as well. So REST API developed in Scala using Akka and Play Framework are not yet supported on AWS Lambda. Single servers can’t handle such a big data set, and, as such, big data architecture can be implemented to segment the data collection, processing, and analysis procedures. To accomplish, all this, it created web crawling agents which follows links and copy all the web-pages content. It also enables cross-language communication like Data Scientist uses R Language for his ML/DL Model Development and if he wants to access data, then he just needs to use another microservice using API Gateway which can be developed in Scala, Python etc. IBM, in partnership with Cloudera, provides the platform and analytic solutions needed to … So Glue will automatically re-deploy our Spark Job on the new cluster, and Ideally, Whenever a job fails, Glue should store the checkpoint of our job and resume it from wherever it fails. This is fundamentally different from data access — the latter leads to repetitive retrieval and access of the same information with different users and/or applications. Big data architecture exists mainly for organizations that utilize large quantities of data at a time –– terabytes and petabytes to be more precise. Big data architecture includes mechanisms for ingesting, protecting, processing, and transforming data into filesystems or database structures. Serverless Architecture simplifies the lifecycle of these types of microservice patterns by managing them independently. It’s like same we do in our Kubernetes cluster using AutoScale Mode, in that we just set the rules for CPU or Memory Usage and Kubernetes automatically takes care of scaling the cluster. In ETL Approach, Generally Data is extracted from the Data Source using Data Processing Platform like Spark and then data is transformed and Then it loaded into Data Warehouse. This platform allows enterprises to capture new business opportunities and detect risks by quickly analyzing and mining massive sets of data. Should have a Data Discovery Service which should charge us only for the execution time of queries. Huawei’s Big Data solution is an enterprise-class offering that converges Big Data utility, storage, and data analysis capabilities. We have full control over our Infra, and we can allocate resources according to our workload. In AWS Platforms, We can configure our DynamoDB Streams with AWS Lambda Function which means whenever any new record gets entered into DynamoDB, it will trigger an event to our AWS Lambda function, and Lambda function will do the processing part and write the results to another Stream, etc. AWS Architecture Center. Define an ETL Job in which Data needs to be pulled from Data Lake and need to run transformations and move the data to Data Warehouse. It allows us to deploy them using our orchestration tools like Kubernetes, Docker, Mesosphere. Now we have to pay for the infra always on which REST API deployed. Developer can just focus only on his code and no need to worry about deployment part and other things. You evaluate possible internal and external data sources and devise a plan to … In the context of Big Data, Let’s say Our Spark’s ETL Job is running and suddenly Spark Cluster gets failed due to many reasons. Set up and use for embedded programming on Windows OS, Stretching the Reach of Implicitly Typed Variables in C#, Spring Boot Microservices — Implementing Circuit Breaker, AWS provides Kinesis Streams and DynamoDB Streams. Scala and other Languages are not supported yet. Business Team needs to analyze their business in various prospects from Data Lake. So We only have to pay for what we store in it, and we don’t need to worry about the cost of infra where we need to deploy our storage. Serverless Stream and Batch Data processing Service provided by Google Cloud in which we can define our Data Ingestion, Processing & Storage Logic using Beam API’s and deploy it on Google Cloud Dataflow. Google Cloud Service in which we can define our business logic to ingest data from any data source like Cloud Pub/Sub and perform Data Transformations on the fly and persist it Into our Data Warehouse like Google Big Query or again to Real-time Data Streams like Google PUB/SUB. Furthermore, sorts or index it so that users can search it effectively. Examples include Sqoop, oozie, data factory, etc. While Google PUB/SUB and Azure EventHub can be also used as a Streaming Serving Layer. So, For those Applications, which needs high performance then we have to think about our performance expectations before we use Serverless Platforms. So We need real-time storage which can scale up in case of a massive increase of incoming data and also scales down if the incoming data rate is slow. It scales up/down according to incoming rate of events, and it can trigger from any Web or Mobile App. So, If security is a major concern for you and you want it very customized, then Containers are a good fit. It means when our deployed function is idle and not being used by any client, we do not have to pay for any infra cost for that. It eases and fastens the process of continuous deployment and automation testing. Azure Cosmos DB and Google Cloud Datastore can also be used for the same. As we know that Kubernetes are very popular nowadays as they provide Container based Architecture for your Applications. So, Developer doesn’t need to worry about the scalability. A container repository is critical to agility. A distributed data system is implemented for long-term, high-detail big data persistence in the data hub and analytics without employing a EDW. But in case of Serverless, In case of no usage, our container can completely shut down, and you have to pay only for the execution time of your Function. Big data architecture is the overarching system used to ingest and process enormous amounts of data (often referred to as "big data") so that it can be analyzed for business purposes. It’s same like we use Nginx for any application and having multiple servers deployed and Nginx automatically takes care of routing our request to any available server. Choosing an architecture and building an appropriate big data solution is challenging because so many factors have to be considered. Its like they launch the things on the fly for us. Obviously, an appropriate big data architecture design will play a fundamental role to meet the big data processing needs. Before we look into the architecture of Big Data, let us take a look at a high level architecture of a traditional data processing management system. There are also various platforms in the market which are providing Serverless Services for various components of our Big Data Analytics Stack. Here we will discuss that how we can set up real-time analytics platform using Serverless Architecture. While Migrating data from our operational systems to Data Lake/ Warehouse,There are two types of approaches. Just Imagine, We have a spark cluster deployed with some 100 Gigs of RAM, and we are using Spark Thrift Server to query over the data, and we have integrated this thrift server with our REST API, and our BI(Business Intelligence) team is using that dashboard. So Batch Queries which needs to be run weekly or monthly, we use Amazon Glacier for that. So This communication among MicroServices is called Composition. But in Serverless, You have to trust on Serverless Platforms for this. Amazon S3 is warm storage, and it is very cheap, and We don’t have to worry about its scalability of size. Then we don’t need to launch a Hadoop or Spark Cluster for that. But Serverless Architecture focuses on decoupling the Compute Nodes and Storage Nodes. NoSQL Service provided by Google Cloud, and it follows serverless architecture and its similar to AWS DynamoDB. Various Cloud providers support Serverless Platforms like AWS Lambda, Google Cloud Function, Azure Functions etc. Here are some points which are lacking in Serverless Platforms as compared to Containers: So Serverless Application is like decoupling all of the services which should run independently. Spark Cluster able to run the analytical queries correctly with only a few queries hit by BI team, If no of concurrent users reached to 50 to 100, then the queries are waiting for the stage, and they will be waiting for earlier queries to get finished and free the resources and then those queries will start executing. So There are two types of Serving Layer : Streams: In AWS, We can choose DynamoDB Streams as our Serving Layer on which Data Processing layer will write results, and further a WebSocket Server will keep on consuming the results from DynamoDB and WebSocket based Dashboard Clients will visualize the data in real-time. Example: AWS S3, Google Cloud Storage, Azure Storage. The Big Data Reference Architecture, is shown in Figure 1 and represents a Big Data system composed of five logical functional components or roles connected by interoperability interfaces (i.e., services). Its main advantage is that Developer does not have to think about servers ( or where my code will run) and he needs to focus on his code. Amazon Glacier is also cheaper storage than Amazon S3, and we used it for achieving our data which needs to be accessed less frequently. OpenFass (Function as a Service) is a framework for building serverless functions on the top of containers (with docker and kubernetes). It is very much similar to AWS Lambda or Google Cloud Function. Example: AWS Glue for Batch Sources and Kinesis Firehose & Kinesis Streams with AWS Lambda for Streaming Sources. The layer where we often do some Data preprocessing like Data Cleaning, Data Validation, Data Transformations, etc. A large bank wanted to build a solution to detect fraudulent transactions submitted through mobile phone banking applications. AWS Lambda is compelling service launched by AWS and based upon Serverless Architecture where we can deploy our code, and AWS Lambda functions and Backend Services manage it. It looks as shown below. The search-engine gathered and organized all the web information with the goal to serve relevant information and further prioritized online advertisements on behalf of clients. AWS Glue is serverless ETL Service launched by AWS recently, and it is under preview mode and Glue internally Spark as execution Engine. It provides a built-in functionality such as self-healing infrastructure, auto-scaling and the ability to control every aspect of the cluster. Google BigQuery is serverless data warehouse service, and Google Cloud Services fully manage it. In this layer, We also perform real-time analytics on incoming streaming data by using the window of last 5 or 10 minutes, etc. Amazon DynamoDB is powerful NoSQL Datastore which built upon Serverless Architecture, and it provides consistent single-digit millisecond latency at scale. It provides Smart Load Balancer which routes the data to our API according to the traffic load. Data Scientists need to explore the data in Data Lake. It’s like we do not have to pay on an hourly basis to any Cloud Platform for our Infra. Otherwise, Go for Container-based architecture. As we can see in the above architecture, mostly structured data is involved and is used for Reporting and Analytics purposes. Self-service Big Data on Spot With Qubole Qubole shows how they built a big data self-service platform on AWS, designed for heterogeneous, distributed processing of petabytes of data. But in ELT Approach, Data is extracted and directly loaded into Data Lake, and Then Data Transformations Jobs are defined and transformed data gets loaded into Data Warehouse. This layer is responsible for serving the results produced by our Data Processing Layer to the end users. The primary Serverless Architecture Providers provides built-in High Availability means our deployed application will never be down. We ingest real-time logs from Kafka Streams and process it in Lambda Functions and generate alerts to Slack, Rocket-Chat, email, etc. Able to ingest any data from different types of Data Sources ( Batch and Streaming ) and should be scalable to handle any amount of data and costing should only be for the execution time of Data Migration Jobs. So, Here is the point, We need a Serverless Query Engine which can serve as many users as per requirement without any degradation in performance. So Our Big Data Platforms must be able to tackle any these situations, and Serverless Architecture is a very high solution of thinking about these problems. Google was first to invent ‘Big Data Architecture' to serve millions of users with their specific queries. Machine Learning and Deep Learning Models are also got offline trained by reading new data from Data Lake periodically. Serverless Container is often used cold start because container got shut down in case of no usage. Serverless Platforms continuously monitor the resource usage of our deployed code ( or functions) and scale up/down as per the usage. But still, Deep level of monitoring is not there like Average time taken by request, and other performance metrics can’t be traced, and also We can’t do deep Debugging also in Cloud-based Serverless Functions. Individual solutions may not contain every item in this diagram.Most big data architectures include some or all of the following components: 1. Analytics tools and analyst queries run in the environment to mine intelligence from data, which outputs to a variety of different vehicles. There is no one correct way to design the architectural environment for big data analytics. NoSQL Datastore: We can use DynamoDB NoSQL Datastore as our Serving layer as well on top of which we can build a REST API, and Dashboard will use REST API to visualize the real-time results. Without a devops process for … Then, After doing some parsing of logs, we are monitoring the metrics and check for any critical event and generate alerts to our notification platforms like Slack, RocketChat, Email, etc. Serverless Compute offers Monitoring by cloud watch, and you can monitor some parameters like concurrent connections and memory usage etc. Big Data Enterprise Architecture in Digital Transformation and Business Outcomes Digital Transformation is about businesses embracing today’s culture and process change oriented around the use of technology, whilst remaining focused on customer demands, gaining competitive advantage and growing revenues and profits. And Not only Decoupling, It should be managed automatically means auto-startup/shutting down of database servers, scaling up / down according to the workload on database servers. As our Big Data Workloads are managed by Serverless Platforms so We don’t need an extra team to manage our Hadoop/Spark Clusters. Our Microservice will be automatically scaled according to its workload, So No need of DevOps Team for monitoring the Resources. Now, we do not know that how much producers can write data means We cannot expect a fixed velocity of incoming data. Moreover, We will charge per 100ms of our execution time. So It means you don’t have to pay for database server infra all the time. Several reference architectures are now being proposed to support the design of big data systems. 2. Here also, pay for whenever you perform any read/write request. We can enable Data Discovery only if we have Data Catalogue which keeps updated metadata about the Data Lake. The ‘Big Data Architecture' features include secure, cost-effective, resilient, and adaptive to new needs and environment. BDC architecture Microsoft SQL Server 2019 Big Data Clusters provides a new way to use SQL Server to bring high-value relational data and high-volume big data together on a unified, scalable data platform. Amazon has launched its Aurora Serverless Database which redefines the way we use our databases. In Batch Data Processing, we have to pull data in increments from our Data Sources like fetching new data from RDBMS once a day or pulling data from Data Lake every hour. This results in the creation of a featuredata set, and the use of advanced analytics. Big Data Analytics can be used for various purposes : So There are few key points which needs to be considered while building Serverless Analytics Solution: Now Let’s say we have a Data Lake on our Cold Storage like S3 or HDFS or Glusterfs using AWS Glue or any other Data Ingestion Platform. The Microservices architecture allows our application to divide into logical parts which can be maintained independently. Google Cloud also has a Cloud ML Engine to provide serverless machine learning services which scales automatically as per Google hardware, i.e., Tensor Processing Units. Google Cloud Platform (GCP): The range of public cloud computing hosting services for computing, storage, networking, big data, machine learning and the internet of things (IoT), as well as cloud management, security, developer tools and application development that run on Google hardware. So it provides seamless integrations with almost every type of client. We use Amazon DynamoDB as Serving Layer for Web and Mobile Apps which needs consistent read and write speed. We can use AWS Cloud DataFlow for AWS Platforms, Google Cloud DataFlow for Google Platforms, Azure DataFactory for Azure Platforms and Apache Nifi in case of open source platforms for defining Streaming Sources like Twitter Streaming or other Social Media Streaming which continuously loading data from Twitter Streaming EndPoints and writing it to our Real-time Streams. We can enable the auto-scaling in Kubernetes and scale up/down our application according to any workload.
