Disadvantages of Cloud Computing:
With all the pace, efficiencies, and improvements that come with cloud computing, there are, evidently, dangers.
Safety has usually been a massive issue with the cloud mainly when it comes to sensitive scientific statistics and monetary statistics. At the same time as policies pressure cloud computing offerings to shore up their safety and compliance measures, it remains an ongoing issue. Encryption protects crucial data, however, if that encryption key is lost, the data disappears.
Servers maintained by means of cloud computing agencies may additionally fall victim to herbal failures, inner bugs, and electricity outages, too. The geographical attainment of cloud computing cuts each way: A blackout in California may want to paralyze customers in the big apple, and a firm in Texas could lose its facts if something causes its Maine-based issuer to crash.
As with all technology, there is a studying curve for each employee and boss. However, with many individuals gaining access to and manipulating facts through a single portal, inadvertent errors can switch throughout an entire system.
Software-as-a-Service (SaaS):
In simple terms, Saas is typically accessed by web browsers. Before SaaS companies have to purchase a compact disk for updating the system. is easy for a small organization but for large organizations updating software is very time-consuming. Thanks to Saas you don't have to purchase a compact disk for updating the system. You have just logged in through the internet and connected the service provider's network to access the particular service.
The simplest real-time example of SaaS is google docs, word processor, google free online. google docs was introduced in October 2012.For using google docs you just need to log in on a web browser.it allows you to write, edit and collaborate with other files. The second simplest example of SaaS IS Dropbox. Dropbox was introduced in 2007.it is a storage service that lets you store, share and collaborate data. You are able to sync videos, images, and other files and back up to the cloud and access them from any device. SaaS commonly uses the net to supply subscription software program services, which are managed via a third-celebration supplier. Following are Saas Example Dropbox, Google Workspace, and Salesforce.
SaaS Advantages:
- Accessible from anywhere
- Cost-effective
- Easy to implement, update, and debug
- Easy to scale
SaaS Disadvantages:
- Increased security risks
- Slower speed
- Loss of control
- Lack of customization
Platform as a Service(PaaS):
Following are PaaS service providers: Google App Engine, Salesforce, windows azure, AppFog, openshift, cloud foundry from Vmware. Paas provides a higher level of abstraction. Pass is used by the software development team. For example, if you want to develop a data-driven application for this you need frameworks like asp.net or java and to store data you need databases like SQL Server or Oracle. you need a web server and host and run applications. purchasing this software and installing it is very time-consuming and expensive. Platform as service is a cloud-based service provider that gives you the ultimate solution to this problem.it reduces development time and deployment speed.
PaaS carriers offer various programming languages for the builders to develop the packages. Some popular programming languages provided with the aid of PaaS companies are Java, the personal home page, Ruby, Perl, and go.
2. Utility frameworks

Public Cloud Computing:
Public clouds are cloud environments normally created from IT infrastructure not owned via the give-up consumer. a number of the largest public cloud carriers consist of Alibaba Cloud, Amazon net services (AWS), Google Cloud, IBM Cloud, and Microsoft Azure.
traditional public clouds usually ran off-premises, however, present-day public cloud vendors have commenced supplying cloud services on clients’ on-premise records facilities. This has made location and possession differences out of date.
All clouds grow to be public clouds whilst the environments are partitioned and redistributed to more than one tenant. price structures are not critical tendencies of public clouds anymore, due to the fact a few cloud vendors permit tenants to use their clouds completely loose. The IT infrastructure used by public cloud companies also can be abstracted and acquired as IaaS, or it is able to be advanced properly right into a cloud platform bought as PaaS.
Private Cloud Computing:
Private clouds are loosely defined as cloud environments totally committed to a single user or group, where the surroundings usually run at the back of that consumer or organization's firewall. All clouds emerge as private clouds while the underlying IT infrastructure is devoted to a single patron with a completely remote right of entry.
but private clouds should not be sourced from on-prem IT infrastructure. organizations are now constructing non-public clouds on rented, vendor-owned records centers located off-premises, which makes any area and possession guidelines out of date.
Hybrid Cloud Computing:
A hybrid cloud is an aggregate of both public and private clouds. Non-critical activity performed on the public cloud and the critical activity performed on the private cloud are stored in the Hybrid cloud.it is easy to use. Hybrid cloud provides more scalability and portability and security.it gives benefits to both public and private cloud it offers secure and scalable public resources. a hybrid cloud provides a high degree of security.
