What are the benefits of Amazon EMR? Drawbacks of AWS EMR

Benefits of Amazon EMR

Amazon EMR has many benefits. These include AWS's flexibility and cost savings over on-premises resource development.

Cost-saving

Amazon EMR costs depend on instance type, number of Amazon EC2 instances, and cluster launch area. On-demand pricing is low, but Reserved or Spot Instances save much more. Spot instances can save up to a tenth of on-demand costs.

Note

Using Amazon S3, Kinesis, or DynamoDB with your EMR cluster incurs expenses irrespective of Amazon EMR usage.

Note

Set up Amazon S3 VPC endpoints when creating an Amazon EMR cluster in a private subnet. If your EMR cluster is on a private subnet without Amazon S3 VPC endpoints, you will be charged extra for S3 traffic NAT gates.

AWS integration

Amazon EMR integrates with other AWS services for cluster networking, storage, security, and more. The following list shows many examples of this integration:

Use Amazon EC2 for cluster nodes.

Amazon VPC creates the virtual network where your instances start.

Amazon S3 input/output data storage

Set alarms and monitor cluster performance with Amazon CloudWatch.

AWS IAM permissions setting

Audit service requests with AWS CloudTrail.

Cluster scheduling and launch with AWS Data Pipeline

AWS Lake Formation searches, categorises, and secures Amazon S3 data lakes.

Its deployment

The EC2 instances in your EMR cluster do the tasks you designate. When you launch your cluster, Amazon EMR configures instances using Spark or Apache Hadoop. Choose the instance size and type that best suits your cluster's processing needs: streaming data, low-latency queries, batch processing, or big data storage.

Amazon EMR cluster software setup has many options. For example, an Amazon EMR version can be loaded with Hive, Pig, Spark, and flexible frameworks like Hadoop. Installing a MapR distribution is another alternative. Since Amazon EMR runs on Amazon Linux, you can manually install software on your cluster using yum or the source code.

Flexibility and scalability

Amazon EMR lets you scale your cluster as your computing needs vary. Resizing your cluster lets you add instances during peak workloads and remove them to cut costs.

Amazon EMR supports multiple instance groups. This lets you employ Spot Instances in one group to perform jobs faster and cheaper and On-Demand Instances in another for guaranteed processing power. Multiple Spot Instance types might be mixed to take advantage of a better price.

Amazon EMR lets you use several file systems for input, output, and intermediate data. HDFS on your cluster's primary and core nodes can handle data you don't need to store beyond its lifecycle.

Amazon S3 can be used as a data layer for EMR File System applications to decouple computation and storage and store data outside of your cluster's lifespan. EMRFS lets you scale up or down to meet storage and processing needs independently. Amazon S3 lets you adjust storage and cluster size to meet growing processing needs.

Reliability

Amazon EMR monitors cluster nodes and shuts down and replaces instances as needed.

Amazon EMR lets you configure automated or manual cluster termination. Automatic cluster termination occurs after all procedures are complete. Transitory cluster. After processing, you can set up the cluster to continue running so you can manually stop it. You can also construct a cluster, use the installed apps, and manually terminate it. These clusters are “long-running clusters.”

Termination prevention can prevent processing errors from terminating cluster instances. With termination protection, you can retrieve data from instances before termination. Whether you activate your cluster by console, CLI, or API changes these features' default settings.

Security

Amazon EMR uses Amazon EC2 key pairs, IAM, and VPC to safeguard data and clusters.

IAM

Amazon EMR uses IAM for permissions. Person or group permissions are set by IAM policies. Users and groups can access resources and activities through policies.

The Amazon EMR service uses IAM roles, while instances use the EC2 instance profile. These roles allow the service and instances to access other AWS services for you. Amazon EMR and EC2 instance profiles have default roles. By default, roles use AWS managed policies generated when you launch an EMR cluster from the console and select default permissions. Additionally, the AWS CLI may construct default IAM roles. Custom service and instance profile roles can be created to govern rights outside of AWS.

Security groups

Amazon EMR employs security groups to control EC2 instance traffic. Amazon EMR shares a security group for your primary instance and core/task instances when your cluster is deployed. Amazon EMR creates security group rules to ensure cluster instance communication. Extra security groups can be added to your primary and core/task instances for more advanced restrictions.

Encryption

Amazon EMR enables optional server-side and client-side encryption using EMRFS to protect Amazon S3 data. After submission, Amazon S3 encrypts data server-side.

The EMRFS client on your EMR cluster encrypts and decrypts client-side encryption. AWS KMS or your key management system can handle client-side encryption root keys.

Amazon VPC

Amazon EMR launches clusters in Amazon VPCs. VPCs in AWS allow you to manage sophisticated network settings and access functionalities.

AWS CloudTrail

Amazon EMR and CloudTrail record AWS account requests. This data shows who accesses your cluster, when, and from what IP.

Amazon EC2 key pairs

A secure link between the primary node and your remote computer lets you monitor and communicate with your cluster. SSH or Kerberos can authenticate this connection. SSH requires an Amazon EC2 key pair.

Monitoring

Debug cluster issues like faults or failures utilising log files and Amazon EMR management interfaces. Amazon EMR can archive log files on Amazon S3 to save records and solve problems after your cluster ends. The Amazon EMR UI also has a task, job, and step-specific debugging tool for log files.

Amazon EMR connects to CloudWatch for cluster and job performance monitoring. Alarms can be set based on cluster idle state and storage use %.

Management interfaces

There are numerous Amazon EMR access methods:

The console provides a graphical interface for cluster launch and management. You may examine, debug, terminate, and describe clusters to launch via online forms. Amazon EMR is easiest to use via the console, requiring no scripting.

Installing the AWS Command Line Interface (AWS CLI) on your computer lets you connect to Amazon EMR and manage clusters. The broad AWS CLI includes Amazon EMR-specific commands. You can automate cluster administration and initialisation with scripts. If you prefer command line operations, utilise the AWS CLI.

SDK allows cluster creation and management for Amazon EMR calls. They enable cluster formation and management automation systems. This SDK is best for customising Amazon EMR. Amazon EMR supports Go, Java,.NET (C# and VB.NET), Node.js, PHP, Python, and Ruby SDKs.

A Web Service API lets you call a web service using JSON. A custom SDK that calls Amazon EMR is best done utilising the API.

Complexity:

EMR cluster setup and maintenance are more involved than with AWS Glue and require framework knowledge.

Learning curve

Setting up and optimising EMR clusters may require adjusting settings and parameters.

Possible Performance Issues:

Incorrect instance types or under-provisioned clusters might slow task execution and other performance.

Depends on AWS:

Due to its deep interaction with AWS infrastructure, EMR is less portable than on-premise solutions despite cloud flexibility.

What is Amazon EMR architecture? And Service Layers

Describe Amazon EMR architecture

The storage layer includes your cluster's numerous file systems. Examples of various storage options.

The Hadoop Distributed File System (HDFS) is scalable and distributed. HDFS keeps several copies of its data on cluster instances to prevent data loss if one instance dies. Shutting down a cluster recovers HDFS, or ephemeral storage. HDFS's capacity to cache interim findings benefits MapReduce and random input/output workloads.

Amazon EMR improves Hadoop with the EMR File System (EMRFS) to enable direct access to Amazon S3 data like HDFS. The file system in your cluster may be HDFS or Amazon S3. Most input and output data are stored on Amazon S3, while intermediate results are stored on HDFS.

A disc that is locally attached is called the local file system. Every Hadoop cluster Amazon EC2 instance includes an instance store, a specified block of disc storage. Amazon EC2 instances only store storage volume data during their lifespan.

Data processing jobs are scheduled and cluster resources are handled via the resource management layer. Amazon EMR defaults to centrally managing cluster resources for multiple data-processing frameworks using Apache Hadoop 2.0's YARN component. Not all Amazon EMR frameworks and apps use YARN for resource management. Amazon EMR has an agent on every node that connects, monitors cluster health, and manages YARN items.

Amazon EMR's built-in YARN job scheduling logic ensures that running tasks don't fail when Spot Instances' task nodes fail due to their frequent use. Amazon EMR limits application master process execution to core nodes. Controlling active jobs requires a continuous application master process.

YARN node labels are incorporated into Amazon EMR 5.19.0 and later. Previous editions used code patches. YARN capacity-scheduler and fair-scheduler use node labels by default, with yarn-site and capacity-scheduler configuration classes. Amazon EMR automatically labels core nodes and schedules application masters on them. This feature can be disabled or changed by manually altering yarn-site and capacity-scheduler configuration class settings or related XML files.

Data processing frameworks power data analysis and processing. Many frameworks use YARN or their own resource management systems. Streaming, in-memory, batch, interactive, and other processing frameworks exist. Use case determines framework. Application layer languages and interfaces that communicate with processed data are affected. Amazon EMR uses Spark and Hadoop MapReduce mostly.

Distributed computing employs open-source Hadoop MapReduce. You provide Map and Reduce functions, and it handles all the logic, making parallel distributed applications easier. Map converts data to intermediate results, which are key-value pairs. The Reduce function combines intermediate results and runs additional algorithms to produce the final output. Hive is one of numerous MapReduce frameworks that can automate Map and Reduce operations.

Apache Spark: Spark is a cluster infrastructure and programming language for big data. Spark stores datasets in memory and executes using directed acyclic networks instead of Hadoop MapReduce. EMRFS helps Spark on Amazon EMR users access S3 data. Interactive query and SparkSQL modules are supported.

Amazon EMR supports Hive, Pig, and Spark Streaming. The programs can build data warehouses, employ machine learning, create stream processing applications, and create processing workloads in higher-level languages. Amazon EMR allows open-source apps with their own cluster management instead of YARN.

Amazon EMR supports many libraries and languages for app connections. Streaming, Spark SQL, MLlib, and GraphX work with Spark, while MapReduce uses Java, Hive, or Pig.
