6 Alasan Kegagalan Startup | NavinoT

1. It’s a Business, Not a Hobby

Alasan paling utama adalah tidak adanya keseriusan dalam pengelolaan. Saya yakin sang penulis adalah seorang blogger handal, atau setidaknya berbakat dalam karyanya. Dari tulisannya bisa membangkitkan minat, serta memupuk kesetiaan pembaca. Namun dalam perjalanannya dia menganggap blogging hanya sebagai hobby, bukanlah sebuah bisnis.

Sebuah bisnis membutuhkan keseriusan, dan perencanaan yang matang, bukan hanya mencoba demi kesenangan. Namun bisnis yang berangkat dari hobby justru mempunyai potensi sukses yang lebih besar.

We've started using Diigo as a social bookmarking tool and would encourage everyone to join our groups (look at the left side of the main page in the Links box). We've got four groups - Math Resources, Science Resources, Professional Resources, and Wired World. Even better, we'd like you to provide comments on how you are using the sites.

Jakarta: A Sinking GIANT? | Indonesia Living Database

idldb.com/?p=61 - Preview

But in Jakarta, there is a fee for everything. Many green spaces have been converted to golf courses for the exclusive use of the rich. The approximately one square kilometer of Monas seems to be the only real public area in a city of more than 10 million. Despite being a maritime city, Jakarta has been separated from the sea, with the only focal point being Ancol, with a tiny, mostly decrepit walkway along the dirty beach dotted with private businesses.

Software as a service - Wikipedia, the free encyclopedia

en.wikipedia.org/...Software_as_a_service - Preview

Software as a Service (SaaS, typically pronounced 'sass') is a model of software deployment whereby a provider licenses an application to customers for use as a service on demand. SaaS software vendors may host the application on their own web servers or download the application to the consumer device, disabling it after use or after the on-demand contract expires. The on-demand function may be handled internally to share licenses within a firm or by a third-party application service provider (ASP) sharing licenses between firms.
As a term, SaaS is generally associated by software professionals and business associates with business software and is typically thought of as a low-cost way for businesses to obtain rights to use software as needed versus licensing all devices with all applications. On-demand licensing enables the benefits of commercially licensed use without the associated complexity and potential high initial cost of equipping every device with the applications that are only used when needed.

- Characteristics of SaaS software include:^[5]^{[dead link]}
  
  network-based access to, and management of, commercially available software
  activities managed from central locations rather than at each customer's site, enabling customers to access applications remotely via the Web
  application delivery typically closer to a one-to-many model (single instance, multi-tenant architecture) than to a one-to-one model, including architecture, pricing, partnering, and management characteristics
  centralized feature updating, which obviates the need for end-users to download patches and upgrades.
  frequent integration into a larger network of communicating software - either as part of a mashup or as a plugin to a platform as a service. (Service oriented architecture is naturally more complex than traditional models of software deployment.)
- Historians can generally classify SaaS architectures as belonging to one of four "maturity levels", whose key attributes are configurability, multi-tenant efficiency, and scalability.^[6] Each level is distinguished from the previous one by the addition of one of those three attributes:
  
  Level 1 - Ad-Hoc/Custom: At the first level of maturity, each customer has its own customized version of the hosted application and runs its own instance of the application on the host's servers. Migrating a traditional non-networked or client-server application to this level of SaaS typically requires the least development effort and reduces operating costs by consolidating server hardware and administration.
  Level 2 - Configurable: The second maturity-level provides greater program flexibility through configurable metadata, so that many customers can use separate instances of the same application code. This allows the vendor to meet the different needs of each customer through detailed configuration options, while simplifying maintenance and updating of a common code base.
  Level 3 - Configurable, Multi-Tenant-Efficient: The third maturity level adds multi-tenancy to the second level, so that a single program instance serves all customers. This approach enables more efficient use of server resources without any apparent difference to the end user, but ultimately comes up against limits in scalability.
  Level 4 - Scalable, Configurable, Multi-Tenant-Efficient: The fourth and final SaaS maturity level adds scalability through a multitier architecture supporting a load-balanced farm of identical application instances, running on a variable number of servers. The provider can increase or decrease the system's capacity to match demand by adding or removing servers, without the need for any further alteration of applications software architecture.
  
  SaaS architectures may also use virtualization, either in addition to multi-tenancy, or in place of it.^[7] One of the principal benefits of virtualization is that it can increase the system's capacity without additional programming. On the other hand, a considerable amount of programming may be required to construct a more efficient, multi-tenant application. Combining multi-tenancy and virtualization provides still greater flexibility to tune the system for optimal performance.^[8] In addition to full operating system-level virtualization, other virtualization techniques applied to SaaS include application virtualization and virtual appliances.
  
  The development of SaaS applications may use various types of software components and frameworks. These tools can reduce the time-to-market and the cost of converting a traditional on-premise software product or building and deploying a new SaaS solution. Examples include components for subscription management, grid computing software, web application frameworks, and complete SaaS platform products.^[9]
