Benefits of Disaster Recovery As a Service

In any business, especially in an IT firm, data is one of the key elements used in running daily operations. There are several ways in which a firm can store and protect its data. In the past, disaster preparation would often require IT staff to travel to off-premise data centers and/or copy corporate data onto tapes. However, advances in technology and computing platforms have enabled the creation of better and more scalable data storage mechanisms. These have paved the way for complete Disaster Recovery as a Service (DRaaS) solutions that can be used instead of internal IT teams.

When data is breached or hacked into, uncontrollable losses will occur. To prevent this, many companies opt to have in place disaster response measures and even dedicated teams for managing such situations.

Today, you’ll find two main categories of computing: cloud computing and hardware server-based computing. This includes the use of DRaaS or traditional backup methods to protect and store data. With current technology, DRaaS offers several advantages over traditional backup and disaster recovery methods.

DRaaS is quite reliable and helps address many challenges, including mobility, portability and high performance, among other features. Traditional disaster recovery does not offer the capabilities that DRaaS can today. In the following section, we’ll look at some of the reasons why you should shift away from other methods and instead rely on DRaaS for disaster recovery.

Fewer Necessary Resources

DRaaS recovery data is stored in the cloud, which reduces the on-premises hardware requirements. Traditional disaster recovery services generally need expensive on-premises hardware and are complex to implement and manage.

DRaaS can be used for a group of critical servers or just a single server, something that may not be economically viable using traditional DR. This means companies can resume limited operations much more quickly.

Cyberattack mitigation

Cyberattacks pose one of the biggest threats to businesses. Earlier this year, the “WannaCry” ransomware attack made headlines when it took over 300,000 computers in 150 countries.

Cyberattacks also come in the form of email phishing scams, whereby scammers trick unwary employees to give out confidential information, and data hacks, whereby cybercriminals gain access to the company’s network and exploit sensitive data.

With DRaaS, you can mitigate these security incidents and prevent a disaster situation. In this type of event, you just invoke your DR plan to bring your applications live in the cloud using the most recent, clean copy of your data. When you have cleaned your production systems from the attack, you can replicate your cloud versions back to your data centre.

That beats negotiating with an attacker for your data back!

Lower Cumulative Costs

Most businesses do not have a good disaster recovery plan because they are concerned about the expenses. In general, backup and disaster recovery can be expensive if you choose methods which necessitate the purchase of hardware. For example, if you want to back up all your data in private servers physically, you must invest in the same number of servers as you have now. DRaaS is a solution provided by a third-party. Therefore, the hardware and software used for your disaster recovery strategy are owned by the service provider. Your initial investment will be small.

Easier testing.

Failover testing is now as simple as pointing and clicking, which takes a lot of the effort (and risk) out of testing. And, as I have made clear, if it isn’t tested regularly, it isn’t reliable.

DRaaS comes with a lot of really good tools for monitoring and protecting critical and sensitive information-and provides auditors with an easily verifiable “paper” trail.

Flexibility

Compared to more traditional methods of backup, DRaaS is much more flexible. The various DRaaS services offer clients more options in how to handle different business systems. Any enterprise using DRaaS solutions can select from a variety of recovery scopes, depending on the type of the disaster. These can include server failure, human-caused disasters, loss of power or building access, data hampering, and much more.

Rapid and Immediate Recovery

Your company can never be sure when a disaster might occur. If one does happen, how much downtime is acceptable? Each second the power is out or your servers fail means huge losses for your organization. With a DRaaS solution in place, you do not have to worry about this: if a disaster strikes, you will be able to restore normal operations within minutes.

Reliable Security

Security in DRaaS is commonly misunderstood, so choose your provider wisely. For example, it’s important to ensure that the provider is compliant with all the relevant regulatory bodies. In addition to making sure the data center itself is physically secure, you should also verify that data is encrypted in-flight and at rest. DRaaS providers should implement automatic systems to monitor the health of your data. For peace of mind, they should also be able to provide you with reports for any specified period.

Streamlines In-House IT Needs

Many small to medium-sized businesses do not have the IT expertise to manage disaster recovery solutions. Managing processes like data recovery or disaster prevention require knowledge of business process and a specific IT skillset. DRaaS allows businesses to leverage the expertise of the consultants providing a more effective way to implement a disaster recovery solution for your business.

Online Database – Key Advantages And Disadvantages

Database in a business scenario is commonly associated with a list of leads or customer information, though in a more technical environment it can also be referred to as Microsoft SQL Server, Oracle or Sybase. Traditionally available offline, databases have also spread across the online horizon delivered over the internet and available on a monthly subscription basis. Though Wikipedia gives you a wide list of online databases, here I’ll mention only about the advantage and disadvantage of getting your data online and forming an online database of your own.

Since the past ten years we have been collecting data using spreadsheets and enhancing our skills to convert it into a database which comes in handy later. Microsoft Access, SQL and Oracle has come along a long way supporting spreadsheets as the complexity of the database increased and it started falling apart. But these databases were available only on a single desktop or accessed over a LAN connection to an in-house server. Easily tackling the desktop spreadsheet applications in the mid-field, web-databases are closing in to score and has become the lifeline of people moving their data online. Most of these web-databases are hosted in a Cloud environment and protected by SSL encryption and a secure log-in with proper User Access Control.

Some advantages of using an Online Database

Online – As the name suggests, an online database can be accessed from a web browser from anywhere in the world. With Cloud Computing coming to the foreground, it is much easier to host an online database in an elastic public cloud making it more scalable and secure.

Elasticity – A web-based-database can hold infinite data and is totally elastic in nature. Whenever there is a surge in data flow, more storage space can be allocated and scaled up and down based on requirement.

Multi-tenancy – A public cloud database is generally multi-tenant in nature. This means the same database can be used by multiple customers on a shared model where you pay only for the space you use.

Pay-Per-Use – Monthly subscription based pay-per-use model makes online databases look quite lucrative where you do not need to invest a huge Cap-Ex on licensed software.

Limitations or disadvantages of an Online Database

Security – One of the gravest concerns of using a web-database is security. With not many security standards available in the Cloud Computing model, most of the users are worried about putting their financial data online.

Switching – Another concern when selecting an online database is switching. Different databases support different formats and switching from one to another becomes a pain thereby increasing switching cost.

Downtime – There are times when the server can be down because of multiple reasons which can lead to huge data loss and inaccessibility thereby causing great losses to customers.

Online database can improve your productivity in many ways and can serve multiple functions. You can customize an online database according to your business workflow or simply use it for data collection and information sharing. Web-based-databases work on different environments, so that is the biggest advantage you can get.

ASUS Looks to Enter the Cloud Storage Market

The word is out, individuals and businesses are turning to the cloud for data storage. For many, the primary reason is that the cloud is the easiest, surest way to back up photos, e-mails, documents and especially data. Others choose the cloud because of freed up space – the cloud makes a great storage option if the sheer volume of data on your computer depletes storage capacity.

But for many computer users, there is a fear of the unknown: Are my files really safe in the cloud, or do I need to back up the backup? The debate has gotten more intense as cloud data storage has become widespread – despite some recent well publicized failures.

The world’s fifth largest PC vendor, Asustek Computer Inc., is looking to expand into the cloud service space in a big way with its unveiling of the ASUS Cloud Platform, an updated rendition of their WebStorage file hosting service.

ASUS announced on May 27th that their rebranded cloud platform will now cost $22.99 US a year for 100 gigabytes of cloud storage. The 70 percent price drop puts them in a prime competitive position with the biggest cloud service providers in the US, which offer the same storage capacity for $99 (DropBox) and $23.88 (Google). They also have a 500 gigabyte option, available for $99.99 a year.

The new Cloud Platform is designed to attract more individual and enterprise users with its simple interface and useful features, and the PC giant expects 50 million users by the end of the year, a rise of over 60% of its current base.

Despite the already large install base, ASUS stated that only about 0.5 – 1% of their users pay subscription fees, as they offer up to 5 gigabytes of storage for free for individual users. The company plans on raising that percentage to over 1% this year, hoping that the improvements in their service and the much smaller entry fee will persuade customers into paying for extra storage.

With the increased reliability on cloud storage to share files across mobile devices, ASUS sees the online data storage industry as an ever-expanding market and an opportunity to branch into the role of a service provider. The hardware giant is looking to follow in the footsteps of companies like Google, Microsoft, and Amazon to provide cloud services to customers at little or no cost, and entice businesses with large storage options at very affordable price points.

In addition to the enterprise and individual customers, ASUS intends to appeal to app developers by offering plenty of useful tools for software coding across different platforms. The tools are meant to “help developers and businesses manage large amounts of data backed by cloud computing technologies” and come included with the service.

ASUS plans to set up a new data center in Taipei to install more servers for its storage platform. The new center is set to open later this year, joining their six current data centers, with three in Taiwan and one in China, the US, and Luxembourg.

The Convenience of Modern Technology

When you are operating a business, regardless of whether that business is large or small, you are going to need to depend upon various types of technology in order to make sure that it runs smoothly. The exact type of technology that is going to be necessary in order to operate the business will differ depending upon the specifics of what the business needs as well as the size of the company. Although there are almost endless variations of items that may be necessary, here are some that you are no doubt going to need to consider.

Computers have become a part of our everyday life, and this is true not only with our business but also in our home lives as well. They can certainly help to make our lives easier, and when used properly, they allow us to get a lot more work done during the day. The type of computer that you are going to need is going to be determined by several different factors. One of the things that you are going to need to consider is if it is necessary for you to have a server with various computers attached to it or if each computer within the company is going to operate independently. You should also consider if you should have a stationary PC or if you should use laptops to allow your employees to travel with their work.

A newer technology that is related to your use of the computer is known as cloud computing. With cloud computing, you access the information that is needed via a remote server instead of a local server. This has many different advantages, provided you choose a company that offers you the security that is necessary. One of the primary benefits is that it can help you with document control, as well as the fact that you can access the information from any computer regardless of where you happen to be.

Other technology is also going to be necessary, such as the business phone systems that may be needed. For some companies, the telephone is simply a way to contact other individuals, but there are times when it is also going to be beneficial for inter-office use. For example, some of the Nortel phone systems, as well as many of the other upgraded phone systems, not only have the standard telephone features that you may need but also have many upgraded features as well. For example, they may allow for conference calling, which is great for having everybody in on the meeting, even if they are not there physically.

As your business continues to grow and expand, you are likely to find many different items that are necessary as far as technology is concerned. Just keep in mind, there are always going to be options that are available that will help to make these technological items more convenient and allow your company to operate smoothly. Just make sure that you take a little bit of time to look at the options that are available, and if necessary, ask someone with the knowledge to help you make a wise decision.

Remote Patient Monitoring Using Mobile and Cloud Computing

INTRODUCTION

The Internet of Things (IoT) is the next paradigm shift, where sensors are connected to the Internet, which collect data for analysis to make our planet more instrumented, interconnected and intelligent. A typical person carries on average one or two mobile devices nowadays. Hence, by leveraging the increasing presence of mobile devices the cost of equipment can be reduced significantly in many industries.

A. Motivation

The ECG iOS application presented in this paper focuses on the health care domain of IoT. With the advancements in embedded information and communication technologies, we can provide intensified healthcare support of senior citizens at homes and retirement homes. This type of technology would be helpful to be providing ECG monitoring facility to senior citizens, athletes and common people. By providing the facility to use these technologies in the home, citizens would be able to live independently for a longer period of time, helping to reduce costs of medical equipment Healthcare is currently facing the challenge of large amount of data that is unstructured, diverse and growing at an exponential rate. Data is constantly streamed through sensors, monitors and instruments in real time that is faster than the medical personnel can keep up with. The advanced techniques and high capacities of cloud computing, processing of a large amount of data can be performed more efficiently support big data analytics.

B. Problem statement

In the healthcare domain of IoT, patients will not have to make as many trips to the doctor anymore, since they can upload the collected data from the sensors to the cloud. This can be achieved for an ECG monitoring application on the mobile device, which will collect the bio-signal data using sensors and then upload to the cloud for keeping a record of the unstructured data. This will reduce the waiting time for the triage at the hospitals and minimize visits and reducing the cost of personnel and administrative operations. This convenience increases the quality of life for the patients as they can enjoy other activities instead of spending time commuting to the hospital/clinic and waiting in long triage queues.

C. Proposed solution

In addition to medical knowledge, various SSE Technologies are involved in IoT based healthcare applications, including microcontroller and sensor technologies, signal processing, communication protocols, system and software design (using well documented design patterns), DBMS, web services, data analysis, and cloud techniques. Such an infrastructure should not only satisfy the basic functional requirements, but also address some key non-functional quality requirements, such as Performance, privacy/security, portability, scalability, flexibility, and cost. Using the idea of IoT and cloud techniques, this paper presents a solution to use an ADC and microcontroller board, which obtains the bio-signal data from a person using sensors and sends it to the mobile device wirelessly using Bluetooth technology. When monitoring the ECG of the patient, the monitored data associated with the ECG waves being displayed on the mobile app is stored in the form of a binary file on the secure digital (SD) card of the device and the user has the ability to upload it to a structured query language (SQL) Server private database. With the proper hardware components like the ADC and microcontroller and the sensors, the solution can monitor the ECG of a person in any environment at low costs, without having to purchase any costly ECG monitoring devices.

DESIGN AND IMPLEMENTATIO

A. Mobile-Based Healthcare Service:

Mobile devices are evolving at a rapid pace in the deployment of healthcare services. Our system is mainly based on real-time long-term health monitoring, catering to the demand of assisted living and health fitness information provider. Thus, the deployment of mobile devices into the mobile healthcare system focuses on several significant features for a medical healthcare system.

B. Communication between Mobile Device and Web Server:

Bluetooth data transmission is applied into the system because Bluetooth facilities are available in numerous smart devices, including portable tablet devices, laptops, personal computers, and even smart TVs. Conceptually; Bluetooth is a open wireless protocol operating in the 2.4-GHz band designed for a medium data rate that averages approximately 2 Mbps.

C. Web Server Cloud Healthcare Service:

Using a Web server healthcare cloud computing system, immediate access to the healthcare tracking system is possible anywhere. The ECG data are displayed in real time on the mobile device. To ensure a seamless and continuous health tracking system, a Web server cloud computing system is implemented into the healthcare service

A. System Architecture

The end-to-end system architecture for this IoT based project involves the hardware, the mobile a application and the cloud. The application has three sub layers named as follows:

Service layer, Platform Application layer and The File Transfer and Writing layer shows how the multiple layers in the system architecture interact with one another. The hardware layer contains the ADC, microcontroller and sensors, which collects the bio signal data and this data is transmitted by the Bluetooth channel on the microcontroller to the Application layer on an IOS device. The Application layer contains three sub layers within the layer itself. The Service Layer is the to op layer in the application layer, which interacts with the hardware layer. The ECG Service is present within the Service layer, which is responsible for retrieval of the bio signal data from the hardware layer and Storing the data in the buffer within ECG Model, which performs the writing of the data.
