Apache Spark Vs Apache Storm - Head To Head Comparison

By KnowledgeHut

In today’s world, the need for real-time data streaming is growing exponentially due to the increase in real-time data. With streaming technologies leading the world of Big Data, it might be tough for the users to choose the appropriate real-time streaming platform. Two of the most popular real-time technologies that might consider for opting are Apache Spark and Apache Storm. One major key difference between the frameworks Spark and Storm is that Spark performs Data-Parallel computations, whereas Storm occupies Task-Parallel computations. Read along to know more differences between Apache Spark and Apache Storm, and understand which one is better to adopt on the basis of different features. Comparison Table: Apache Spark Vs.

(YARN, Mesos)If a process fails, the supervisor process starts automatically.12.Throughput100k records per node per second10k records per node per second13.PersistenceMapStatePer RDD14.ProvisioningBasic monitoring using GangliaApache Ambaripache Spark: Apache Spark is a general-purpose, lighting fast, cluster-computing technology framework, used for fast computation on large-scale data processing. It can manage both batch and real-time analytics and data processing workloads. Spark was developed at UC Berkeley in the year 2009. Apache Storm:Apache Storm is an open-source, scalable fault-tolerant, and real-time stream processing computation system. It is a framework for real-time distributed data processing, which focuses on stream processing or event processing. It can be used with any programming language and can be integrated using any queuing or database technology. Apache Storm was developed by a team led by Nathan Marz at BackType Labs. Apache Spark Vs. Apache StormProcessing Model: Apache Storm supports micro-batch processing, while Apache Spark supports batch processing. Programming Language:Storm applications can be created using multiple languages like Java, Scala and Clojure, while Spark applications can be created using Java and Scala.Stream Sources:For Storm, the source of stream processing is Spout, while that for Spark is HDFS. Messaging:Storm uses ZeroMQ and Netty as its messaging layer while Spark is using a combination of Nettu and Akka for distributing the messages throughout the executors. Resource Management:Yarn and Meson are responsible for resource management in Spark, while Yarn and Mesos are responsible for resource management in Storm. Low Latency: Spark provides higher latency as compared to Apache Storm, whereas Storm can provide better latency with fewer restrictions.Stream Primitives:Spark provides with stream transforming operators which transform DStream into another, while Storm provides with various primitives which perform tuple level of processing at the stream level (functions, filters). Development Cost:It is possible for Spark to use the same code base for both stream processing and batch processing. Whereas for Storm, the same code base cannot be used for both stream processing and batch processing. State Management: The changing and maintaining state in Apache Spark can be updated via UpdateStateByKey, but no pluggable strategy can be applied in the external system for the implementation of state. Whereas Storm does not provide any framework for the storage of any intervening bolt output as a state. Hence, each application has to create a state for itself whenever required. Message Delivery Guarantees (Handling the message level failures):Apache Spark supports only one message processing mode, viz, ‘at least once’, whereas Storm supports three message processing modes, viz, ‘at least once’ (Tuples are processed at least one time, but can be processed more than once), ‘at most once’ and ‘exactly once’ (T^uples are processed at least once). Storm’s reliability mechanisms are scalable, distributed and fault-tolerant. Fault-Tolerant:Apache Spark and Apache Storm, both are fault tolerant to nearly the same extent. If a process fails in Apache Storm, then the supervisor process will restart it automatically, as the state management is managed by Zookeeper, while Spark restarts its workers with the help of resource managers, who may be Mesos, YARN or its separate manager.Ease of Development: In the case of Storm, there are effective and easy to use APIs which show that the nature of topology is DAG. The Storm tuples are written dynamically. In the case of Spark, it consists of Java and Scala APIs with practical programming, making topology code a bit difficult to understand. But since the API documentation and samples are easily available for the developers, it is now easier. Summing Up: Apache Spark Vs Apache StormApache Storm and Apache Spark both offer great solutions to solve the transformation problems and streaming ingestions. Moreover, both can be a part of a Hadoop cluster to process data. While Storm acts as a solution for real-time stream processing, developers might find it to be quite complex to develop applications due to its limited resources. The industry is always on a lookout for a generalized solution, which has the ability to solve all types of problems, such as Batch processing, interactive processing, iterative processing and stream processing. Keeping all these points in mind, this is where Apache Spark steals the limelight as it is mostly considered as a general-purpose computation engine, making it a highly demanding tool by IT professionals. It can handle various types of problems and provides a flexible environment to in. Moreover, developers find it to be easy and are able to integrate it well with Hadoop.

What is Power BI Used For - Practical Applications Of Power BI

By KnowledgeHut

Organizations deal with lots of data regularly. But in case you are not able to access or connect with that important data, you are not yielding anything. You are keeping your organizations away from getting the value. Microsoft Power BI will help you solve this problem with the help of a powerful business intelligence tool that mainly stresses on Visualization. Microsoft Power BI is a fundamental programming framework for organizations with huge amounts of disparate data developed during normal business operations. Power BI has numerous uses in building a software system. Let’s see the practical uses of Power BI below:Visualization = Inbuilt featureServer-Level Data ManagementAnalytics With Internal Software SystemsProvide complex data within software and appsStreamline Organizational ProcessesVisualize Details EasilyEnhance the marketingReal-Time look at the company’s financial performanceCreate Consistent Reporting Standards 1. Visualization = Inbuilt featureData Visualization is very crucial for human management in business systems. The computer programs are written in coding language whereas business people need to be able to visualize and understand the business data. Microsoft Power BI provides such tools that will let you visualize key data points accurately from various sources in a single dashboard. Power BI integration with Cortana can visualize data, interact with it in your OS, and search your data with Cortana’s powerful AI systems.2. Server-Level Data ManagementIn businesses, data comes from various sources. Most of those sources reach the server at some point. Power BI tools let you manage all the business-related data at the server level with the goal that you have more extensive and complete information systems than the data you collected from a program working on a few PCs. 3. Analytics With Internal Software SystemsYour business needs to access data from the complete software system to manage it. Power BI merges with any software platform used to manage the businesses. This consists of mail management, social media platforms, accounting software, CRMs, and traditional data platforms like Azure and MySQL. Multiple dashboards for data management are integrated to form Integrated data management. If the businesses use integrated data management then the businesses need not use multiple dashboards for managing the data. 4. Provide complex data within software and appsPower BI takes input from various sources and provides that data in various contexts, including embedded within your own apps through API by Microsoft. Moreover, Power BI offers tools to manage businesses allowing app customization. It also provides a product value-add feature that is used to track and identify the key data sets regarding the product or service. 5. Streamline Organizational Processes The departments such as Sales, marketing, operations, HR, and so on in the organizations need their own data sets, KPIs, and their own data management systems. Power BI offers specific functionality to the businesses in the form of a data management system/app to streamline the processes from different departments. It let the businesses use the templates for intuitive dashboards and reporting systems instead of creating a system part-wise for your business. It gives your teams the capability to manage quality and efficiency without software customization. 6. Visualize Details EasilyPower BI helps businesses to check any kind of details to ensure that the business is running smoothly. While some enterprises track a small amount of inventory, some businesses track sales calls (made by the sales team members). These data sets are designed with Power BI algorithm and delivered in a readable and easily understandable format.7. Enhance the marketingBusinesses spend intensely on online marketing to attract customers. But the huge mass is failing to convert while researching the solutions to their uniques problems online. In this case, Power BI helps you create a chart to track the user behavior all through their online visit. 8. Real-Time look at the company’s financial performanceFinancial issues have an enduring effect on your organization, particularly if it's totally all of a sudden. Microsoft Power BI gives you understanding into the performance of the organizations at numerous levels. With Power BI, you can gaze into teams productivity, top-selling products, the income created by a specific division and numerous different perspectives. With Power BI, you will be able to get immediate attention on sudden financial drops and will be able to fix the issues before it turns into a huge concern. 9. Create Consistent Reporting StandardsEvery organization relies on applications from accounting to sales for their day-to-day job duties. You will not always get a reporting feature in these programs and if you get, the format varies from app to app. Using Power BI, you can pull the data and generate reports to provide you organizational standards. It is less hectic for the managers and takes less time to get the data if it is presented in the same format and style each time.Use-cases of Power BIThere is no doubt that Big Data has big potential today. Most of the companies using Power BI have started enjoying the real benefits such as higher efficiency, improved performance, and more efficient use of their data. Here are some of the real-world examples of Power BI that will tell you how companies are reaping commercial success with Power BI.1. MediaComMediaCom is the world's most famous media agency and the largest cable television provider was in need of the module that can easily measure and represent the health of a large number of diversified data sets. For this problem, they found the solution i.e. ‘health check’ which is able to capture every surface of a multi-platform media in one single score, including paid media effectiveness, earned media effectiveness, the ratio of earned-to-paid media, realized customer value, and longitudinal performance. The feature ‘health-check’ is built on Power BI that provides a campaign dashboard, a collaborative site where the account team can ask their queries to the customers. With the adoption of Power BI, the company yielded increased optimization checks for campaigns from weekly to daily basis. 2. Carnegie Mellon UniversityCarnegie Mellon University (CMU), a global research university known for its world-class studies was looking for some option that can optimize the power (energy) and operational efficiency in buildings around the globe.The university installed a PI system and integrated automation system of the whole building. Also, they installed lights, ventilation, air quality, weather, and security data sources. At that point, they included Power BI for Office 365 to give custom-reporting abilities to all the constant information created by the different frameworks, furnishing employees with maps, visualizations, and dashboards indicating data, for example, building types, geographic areas, and power consumption. This data empowers employees to identify the environment, and show them to reduce energy usage. With Power BI installed, CMU identified 30% less energy consumption.3. HeathrowHeathrow Airport, a UK based travel, and transportation industry uses Power BI to make the travel of the passengers less stressful. This airport uses Power BI to visualize the real-time passenger’s traffic at the airport and enable employees to be prepared with the traffic changing conditions. With Power BI adoption, they will be able to connect with a wide scope of data sources with fewer efforts and use this data to run Heathrow airport smoothly than ever before.
