What Are the Advantages and Disadvantages of Cloud Computing?

Cloud services are the needs of businesses and industries of all sizes and geographies. The number of respondents adopting cloud in both public and private has increased manifolds. According to a report by Dell, the companies that invest in cloud, mobility, and big data enjoy up to 53% faster revenue growth than their counterparts. More and more organizations are adopting cloud technology to run the business effectively, to serve their customers in a better way and to overall increase their margin of profit.Benefits of Cloud ComputingHere is the detailed list of various benefits offered by cloud computing:Cost-effective: The cost of hardware and equipment is low and these services are free from capital expenditure. The organizations need not have large IT teams to handle and maintain the cloud data centre operations. The maintenance cost is also low and the occurrence of downtime is also less which means the organizations need not spend a huge amount of money for fixing potential issues. Cloud computing works on the principle of pay-as-you-go, which means you need to pay money only for the services that you use, and you need not invest in additional features that do not serve you. Companies need to pay for servers and infrastructure as and when needed. More services can be commissioned for times of need and the services not being used can be de-provisioned. This further cuts down the expenditure. Owing to the ROI of these technologies, the return is much higher than the costs.Scalability: Using a cloud service provides companies with an option to scale up or down their IT departments according to their business needs and requirements. You can upgrade the capacity of your cloud without investing in physical infrastructure. Hence these services are ideal for companies with volatile bandwidth demands. The cloud computing service provider handles the expensive upgrades and their installations. The scalability provided by these services reduces the risks with operational failures and maintenance. This also leads to time-effective solutions as most of the complicated tasks are handled by your cloud service providers. Hence the demands are in alignment with the workloads. An example of the scalability feature of cloud computing is in sales promotion; the capacity can be scaled when the sales promotion is very popular, and when the sale is over, the capacity can be cut down to reduce the cost.Mobility: For more and better inclusion, cloud services are easily accessible on smartphones and mobile devices. According to a report, over 2.6 billion smartphones are being used around the world for cloud services. It is also beneficial for people staying away from their corporate offices, as they can easily access these services from their point of convenience and keep themselves updated with the clients and their work. Most of the cloud providers offer 24*7 services with an uptime of 99.9%. Even some of the functions are available offline as well, which is highly convenient for the workers and they can access the services from anywhere at any time. Adding to this, all the upgrades and updates are done automatically by the service providers further cutting down the IT costs.Data security: Data security is a concern for many organizations while adopting cloud-based services. With the increased rate of data theft in organizations, it becomes a priority to secure data, files, and downloads. Cloud services provide encryption of data being shared over multiple networks and data that are stored in the database. The data can be easily restored if something goes down with your device. The data can be deleted from other locations to avoid falling in the wrong hands. Cloud storage providers implement baseline protections for their platforms and the data they process, such as authentication, access control, and encryption.Disaster recovery: The control system to deal with any situation is a deciding factor for the success of any business. Though many measures are taken to prepare for potential risks that might occur, there are situations that go out of control. A downtime of small duration can severely affect your revenue. Apart from this, data loss is a major concern for all organizations. The data stored in the cloud can be easily restored and recovered even when your physical system goes down. Cloud-based services provide quick and effective data recovery from most of the potential emergency conditions like power outages and natural disasters.Automatic updates: Your system will be regularly updated by your cloud computing service provider. Hence this saves the trouble of waiting for the system updated to get installed. This also saves the efforts of the IT department to keep a check on the new updates being introduced and install them. Immediate upgrades put new features and functionality provided automatically into workers’ control to make them more productive. Software enhancements are typically released quite frequently unlike the homegrown or purchased software that might have major new releases only once a year or so and take significant time to roll out.Enhanced collaboration: For businesses operating with a large number of employees, collaboration among them is a priority. Cloud computing facilitates this process. The members of a team can easily and securely view and share the data across a cloud-based platform. To enhance the engagement of the employees, some of these services provide social spaces to connect the employees. The cloud services authorize a diverse group of people virtually and allow them to share information through shared storage. If you are working on a project that is spread across different locations, you could use cloud computing to give employees, clients and third parties access to the same files. You could also choose from the different cloud computing models to make it easy for you to share your records with your managers and higher authority.Disadvantages of cloud computing:Every technology has a positive and a negative side and both must be considered before adopting it. Though cloud computing is a huge success and it boasts of many reliable features, but there are some factors that might create a problem for your company. Here, we discuss some of the downsides of cloud computing and how it affects the organizations:Downtime: Good internet connectivity is a must in cloud computing. The cloud computing service provider may face power outage, internet connectivity loss, or service maintenance that might affect your process. If your internet speed is slow, it might affect the process adversely, since most of the services are online. Other than the internet, there is no other way to access data on the cloud, so there is a lot of dependency on internet connectivity. You must have a reliable and consistent internet service to operate smoothly with the cloud. Lower bandwidth: Many cloud service providers limit the bandwidth range of usage. If the need occurs to expand the bandwidth, then it might increase the cost.Limited control: Cloud services are completely managed and owned by service providers operating remotely. Hence the employees have limited control over backend features.Security threat in the cloud: Since all of your data is available online with the cloud, it increases the possibility of data theft. You should be well aware of the fact that all your company's sensitive information is being shared with a third-party cloud computing service provider. Thus it should be trustworthy enough since hackers might have accessed this information. Though the cloud computing vendors ensures that their services have sophisticated data security systems, but there have been many occurrences of data breaches via hacking, a disgruntled employee, or careless username/password security.Vendor lock-in: Your company might face some serious challenges while migrating from one cloud computing vendor to another. It might lead to configuration complexities, support issues, and hence additional charges.We hope that this article gave you a clear understanding of how AWS services work. You can understand how cloud computing works by making yourself familiar with these services.

A Quick view of SAFe® Agile has gained popularity in recent years, and with good reason. Teams love this approach that allows them to get a value to the customer faster while learning and adjusting to change as needed. But teams often don’t work in isolation. Many teams work in the context of larger organizations.  Often Agile doesn’t fit their needs. Some teams need an Agile approach that scales to larger projects that involve multiple teams.   It’s possible to do this. That’s where the Scaled Agile Framework, or SAFe®, can help.Why SAFe® is the best scalable framework?The Scaled Agile Framework is a structured Agile approach for large enterprises. It’s prescriptive and provides a path for interdependent teams to gain the benefits of using an Agile approach.Scaled Agile provides guidance not only at the team level but also at the Program and Portfolio levels. It also has built-in coordinated planning across related teams who are working in Release Trains.These planning increments allow teams to plan together to work with customers and release value frequently in a way that’s sustainable to teams.And it supports continuous improvement.It’s a great way for large companies to maintain structure and roll out Agile at a large scale.  What is SAFe® 4.5? Scaled Agile, otherwise known as SAFe®, was initially released in 2011 by Dean Leffingwell as a knowledge base for enterprises to adopt Agile. Over the years it has grown and evolved. SAFe® 4.5 was released on June 22, 2017, to accommodate improvements to the framework. Following are some of the key improvements in SAFe® 4.5:Essential SAFe® and ConfigurabilityInnovation with Lean Startup and Lean UXScalable DevOps and Continuous DeliveryImplementation roadmapBenefits of SAFe® 4.5 to companies:Organizations who adopt SAFe® 4.5 will be able to gain the following benefits:1) Test ideas more quickly. SAFe® 4.5 has a build-in iterative development and testing. This lets teams get faster feedback to learn and adjust more quickly.2) Deliver much faster. The changes to SAFe® 4.5 allow teams to move complex work through the pipeline and deliver value to the customer faster.3) Simplify governance and improve portfolio performance. Guidance and support have been added at the Portfolio level to guide organizations in addressing Portfolio-level concerns in a scaled agile context. SAFe® 4.5 - Key areas of improvements:A. Essential SAFe® and ConfigurabilityFour configurations of SAFe® that provide a more configurable and scalable approach:Essential SAFe®: The most basic level that teams can use. It contains just the essentials that a team needs to get the benefits of SAFe®.Portfolio SAFe®: For enterprises that implement multiple solutions that have portfolio responsibilities such as governance, strategy, and portfolio funding.Large Solution: Complex solutions that involve multiple Agile Release Trains. These initiatives don’t require Portfolio concerns, but only include the Large Solution and Essential SAFe® elements.  SAFe® Full SAFe®: The most comprehensive level that can be applied to huge enterprise initiatives requiring hundreds of people to complete.Because SAFe® is a framework, that provides the flexibility to choose the level of SAFe® that best fits your organization’s needs.B. Innovation with Lean Startup and Lean UXRather than creating an entire project plan up-front, SAFe® teams focus on features. They create a hypothesis about what a new feature will deliver and then use an iterative approach to develop and test their hypothesis along the way. As teams move forward through development, they perform this development and test approach repeatedly and adjust as needed, based on feedback. Teams also work closely with end users to identify the Minimum Viable Product (MVP) to focus on first. They identify what will be most valuable to the customer most immediately. Then they rely on feedback and learning as they develop the solution incrementally. They adjust as needed to incorporate what they’ve learned into the features. This collaboration and fast feedback and adjustment cycle result in a more successful product.  C. Scalable DevOps & Continuous DeliveryThe addition of a greater focus on DevOps allows teams to innovate faster. Like Agile, DevOps is a mindset. And like Agile, it allows teams to learn, adjust, and deliver value to users incrementally. The continuous delivery pipeline allows teams to move value through the pipeline faster through continuous exploration, continuous integration, continuous deployment, and released on demand. DevOps breaks down silos and supports Agile teams to work together more seamlessly. This results in more efficient delivery of value to the end users faster. It’s a perfect complement to Scaled Agile.D. Implementation RoadmapSAFe® now offers a suggested roadmap to SAFe® adoption. While change can be challenging, the implementation roadmap provides guidance that can help with that organizational change.Critical Role of the SAFe® Program ConsultantSAFe® Program Consultants, or SPCs, are critical change agents in the transition to Scaled Agile.Because of the depth of knowledge required to gain SPC certification, they’re perfectly positioned to help the organization move through challenges of change.They can train and coach all levels of SAFe® participants, from team members to executive leaders. They can also train the Scrum Master, Product Owners, and Agile Release Train Engineers, which are critical roles in SAFe®.The SPC can also train teams and help them launch their Agile Release Trains (ARTs).And they can support teams on the path to continued improvement as they continue to learn and grow.The SPC can also help identify value streams in the organization that may be ready to launch Agile Release Trains.The can also help develop rollout plans for SAFe® in the enterprise.Along with this, they can provide important communications that help the enterprise understand the drivers and value behind the SAFe® transition.       How SAFe® 4.5 is backward compatible with SAFe® 4.0?Even if your organization has already adopted SAFe® 4.0, SAFe® 4.5 has been developed in a way that can be easily adopted without disruption. Your organization can adopt the changes at the pace that works best.Few Updates in the new courseware The courseware for SAFe® 4.5 has incorporated changes to support the changes in SAFe® 4.5.They include Implementing SAFe®, Leading SAFe®, and SAFe® for Teams.Some of the changes you’ll see are as follows:Two new lessons for Leading SAFe®Student workbookTrainer GuideNew look and feelUpdated LPM contentSmoother lesson flowNEW Course Delivery Enablement (CDE) Changes were made to improve alignment between SAFe® and Scrum:Iteration Review: Increments previously known as Sprints now have reviews added. This allows more opportunities for teams to incorporate improvements. Additionally, a Team Demo has been added in each iteration review. This provides more opportunity for transparency, sharing, and feedback.Development Team: The Development team was specifically identified at the team level in SAFe® 4.5. The development team is made up of three to nine people who can move an element of work from development through the test. This development team contains software developers, testers, and engineers, and does not include the Product Owner and Scrum Master. Each of those roles is shown separately at the team level in SAFe® 4.5.Scrum events: The list of scrum events are shown next to the ScrumXP icon and include Plan, Execute, Review, and Retro (for a retrospective.)Combined SAFe® Foundation Elements SAFe® 4.0 had the foundational elements of Core Values, Lean-Agile Mindset, SAFe® Principles, and Implementing SAFe® at a basic level.SAFe® 4.5 adds to the foundation elements by also including Lean-Agile Leaders, the Implementation Roadmap, and the support of the SPC in the successful implementation of SAFe®.Additional changes include: Communities of Practice: This was moved to the spanning palette to show support at all levels: team, program, large solution, and portfolio.Lean-Agile Leaders: This role is now included in the foundational level. Supportive leadership is critical to a successful SAFe® adoption.SAFe® Program Consultant: This role was added to the Foundational Layer. The SPC can play a key leadership role in a successful transition to Scaled Agile.Implementation Roadmap: The implementation roadmap replaces the basic implementation information in SAFe® 4.0. It provides more in-depth information on the elements to a successful enterprise transition to SAFe®.Benefits of upgrading to SAFe® 4.5With the addition of Lean Startup approaches, along with a deeper focus on DevOps and Continuous Delivery, teams will be situated to deliver quality and value to users more quickly.With improvements at the Portfolio level, teams get more guidance on Portfolio governance and other portfolio levels concerns, such as budgeting and compliance.  Reasons to Upgrade to SAFe® 4.5 Enterprises who’ve been using SAFe® 4.0 will find greater flexibility with the added levels in SAFe® 4.5. Smaller groups in the enterprise can use the team level, while groups working on more complex initiatives can create Agile Release Trains with many teams.Your teams can innovate faster by using the Lean Startup Approach. Work with end users to identify the Minimum Viable Product (MVP), then iterate as you get fast feedback and adjust. This also makes your customer more of a partner in development, resulting in better collaboration and a better end product.Get features and value to your user community faster with DevOps and the Continuous Delivery pipeline. Your teams can continuously hypothesize, build, measure, and learn to continuously release value. This also allows large organizations to innovate more quickly.Most Recent Changes in SAFe® series - SAFe® 4.6Because Scaled Agile continues to improve, new changes have been incorporated with SAFe® 4.6. with the addition of five core competencies that enable enterprises to respond to technology and market changes.Lean Portfolio Management: The information needed for how to use a Lean-Agile approach to portfolio strategy, funding, and governance.Business Solutions and Lean Systems: Optimizing activities to Implement large, complex initiatives using a Scaled Agile approach while still addressing the necessary activities such as designing, testing, deployment, and even retiring old solutions.DevOps and Release on Demand: The skills needed to release value as needed through a continuous delivery pipeline.Team and Technical Agility: The skills needed to establish successful teams who consistently deliver value and quality to meet customer needs.Lean-Agile Leadership: How leadership enables a successful agile transformation by supporting empowered teams in implementing agile practices.

How Start Ups Can Benefit From Cloud Computing?

From nebulous beginnings, the cloud has grown to a platform that has gained universal acceptance and is transforming businesses across industries. Companies that have adopted cloud technology have seen significant payoffs, with cloud based tools redefining their data storage, data sharing, marketing and project management capabilities. The easy availability of affordable cloud infrastructure has made it so easy to set up new businesses that the economy is all set for a start up boom which has its head, so to speak, in the cloud! With the advent of this new technology, complete newbie’s in the market are able to hold their own against established market players—by achieving an amazing quantum of work using skeleton manpower resources. Recently, a popular ad doing the rounds on TV showed a long haired youth conducting business from a cafe on his HP Pavilion laptop, where he is ridiculed by some well heeled middle aged businessmen on their coffee break. Back at their office, they find that this youngster is the new investor that their boss has been heaping accolades on. “Where’s your office?” one of them asks the young man…to be laughingly told that he carries his entire office in his laptop! And that, typically, is how the new-age start up business looks. We have heard many stories of how a clever idea has turned a tidy profit for a smart entrepreneur working out of his laptop. While cloud computing is pushing the boundaries of science and innovation into a new realm, it is also laying the foundation for a new wave of business start ups. New ventures in general suffer from a lack of infrastructure, manpower and funding…and all these three concerns are categorically addressed by the cloud. Moving to the cloud minimizes the need of huge capital investments to set up expensive infrastructure. For nascent entrepreneurs, physical hardware and server costs used to be formidable given the limited budgets at their disposal. Seed money was also required to hire office space, promote the business and hire workers. Today, thanks to cloud technology, getting a new business off the ground and running costs virtually nothing. Most of the resources and tools that new ventures need are available on the cloud at minimal costs, in fact quite often at zero costs, making this a powerful value proposition for small businesses. A cloud hosting provider such as AWS can enable you to go live immediately, and will even scale up to your requirement once your business expands. Small businesses can think and dream big with the cloud. When it comes to manpower resources, it takes just a handful of people to work wonders using the online resources that are at their disposal. If you have a brilliant idea and have a workable plan for execution, you can comfortably compete neck to neck with market leaders. The messaging sensation WhatsApp was started in 2009 by just two former Yahoo employees who leveraged the power of the internet – and this goes to show that clever use of technology can completely eliminate the need for a sizeable manpower pool. Start ups have always been more agile than their large scale counterparts, and the cloud helps them take this a step further. Resources can be scaled up or down in no time, whereas in traditional environments it would have taken many days, considerable planning and funds to add hardware and software. Cloud computing also helps improve collaboration across teams, often across geographies. Data sharing is instantaneous, and teams can work on a task together in real time regardless of their location. Powered by the cloud, small businesses operate with shoestring budgets and key players in different continents. All their accounting, client data, marketing and other business critical files can be stored online and are accessible from anywhere. These online tools can be accessed and utilised instantly, and underpin all the crucial processes on which these businesses thrive. Strategic financial decisions are made after garnering insights from cloud-based accounting software. E-invoicing helps settle bills in a fraction of the time of traditional billing systems, and client queries are answered quickly through cloud-based management systems—saving precious time and increasing customer satisfaction levels to an all-time high. Whether at home, on vacation or on the phone, businesses can oversee sales, replenish products and plan new sales strategies. That’s a whole new way of doing business, and seems to be very successful! An estimate by Cloudworks has put the anticipated cloud computing market at over $200 billion by the year 2018. As Jeff Weiner, CEO of LinkedIn, succinctly put it, the cloud “makes it easier and cheaper than ever for anyone anywhere to be an entrepreneur and to have access to all the best infrastructure of innovation.” With cloud technology rapidly levelling the playing field between nascent and established businesses, it is anybody’s guess as to just how many new start ups will burst into the scene in the next few years. Hoping that the blog has helped you gain a clear understanding of the importance of Cloud Computing.  To gain more knowledge on what cloud computing has to offer, take a look at other blogs as well as the AWS certifications that we have to offer or enrol yourself for the AWS Certification Training course by KnowledgeHut.
