Mobile Cloud Computing (MCC) is a combination of wireless networks, mobile computing, and cloud computing created to bring rich resources to network operators, mobile users, and cloud computing providers. Recently, there has been an enormous increase in the use of tablets, smart phones, and other mobile devices. As a result, many mobile cloud platforms have occurred and are becoming more popular every day. However, some websites have a convenient mobile version that works well, whereas some other websites either do not have a mobile version or it works bad and lacks many functions ( What is mobile cloud computing, 2017). Thus, the following analysis shows how three different websites work on four different devices, namely a low-tier phone, mid-tier phone, high-tier phone, and desktop, and scores these websites according to the scale at http//ready.mobi.
IMDB.com
The overall results of the test of imdb.com showed an extremely poor performance of this website with the score only 0.84. Many considerable test failures were detected, which can directly impact the user. The most prominent disadvantage of this site was its weight regarding the bytes downloaded. The size of the tested page was very high, which would negatively affect user experience. Additionally, seven major failures were detected. The most significant failure that was found during the test was the ETag support, namely, the website did not contain Etag headers, which speed up future page loads and enable client-side caching.
Some major differences in page composition were detected. The desktop device and the high-tier phone loaded a maximum of images and JavaScript elements. The desktop also loaded a maximum of HTML elements of the website.
Wikipedia.org
According to the results of the test of Wikipedia.org, three major failures were detected. The most significant of them is the DOM element count being high at 919, while the recommended number of DOM elements is less than 700, since the page becomes too complex, which negatively affects user experience.
The performance score of this website is good and equals 3.68. The size of the site is optimal; the use of pictures is minimal. Overall, the results showed that the desktop device rendered maximum HTML, CSS, and JavaScript elements. The high-tier phone rendered a little fewer elements, and mid-tier and low-tier phones almost did not render JavaScript elements at all and minimum HTML and CSS elements.
Amazon.com
The results of the test of amazon.com showed the moderate performance of this website with the score 1.76. Overall, six major failures were detected. The most prominent of them is the image crunch, namely, the image becomes 50% smaller after optimization. All images should be optimized in order to reduce the file size. Additionally, the appropriate type of image should be used for every image asset.
The principal differences between the analyzed devices are the same as with the two previous websites. Namely, the low-tier phone loads very few HTML, CSS, and JavaScript elements, and a minimum of images; the mid-tier phone also loads few elements but more than the low-tier phone; the high-tier phone loads the average number of elements in each category; finally, the desktop loads maximum elements of the website.
Conclusion
In conclusion, it can be stated that despite the fact that mobile devices are very popular today, there are still not many websites, even among the most popular ones, that are adapted to these devices. Certainly, there are fewer functions in the mobile version of all websites that have them. Additionally, it is difficult to create the adequate mobile version of some websites, as they contain visual elements that are usually of a big size, which makes it inconvenient to use them on mobile devices. Therefore, in order to create a good mobile-cloud ecosystem, the mentioned four devices should work together, namely, they should have their own versions of the same website but without significant differences and contain the elements that have the most appropriate size for each of these devices ( What is mobile cloud computing, 2017).
